Centripetal Acceleration | Mechanics

Image
  What is Centripetal Acceleration? Have you ever been riding in a car and felt like the seatbelt was pulling you back into your seat? This is an example of centripetal acceleration. It's a type of acceleration that pulls or pushes objects towards the center of a circle. Centripetal acceleration is not just limited to cars, but can also be seen when watching an object being thrown off of a bridge or mountain. The forces acting on R are known as centripetal force. These are always directed toward the center of the rotation, to keep an object close to rotating around it. This is important for things like satellites orbiting Earth, otherwise they would fly off into space. Check out this informative article to learn more about what centripetal acceleration is and how it affects other aspects of our lives! What is Centripetal Acceleration? The definition of centripetal acceleration Centripetal acceleration is the inward, centering force that an object feels around a rotating object. Her...

Physics of a Freely Falling Body | Mechanics

Image
 Physics of a Freely Falling Body. What is the physics behind the so-cal led "free-falling" body? The word “free” in “free fall” means that the only force acting on the falling object is gravity. There are no other forces to affect it. As a result, when an object falls freely, it falls at a constant rate of acceleration known as gravitational acceleration. This article provides an overview of how free-falling bodies behave in two different situations: when they are not accelerating or when they are accelerating uniformly under gravity.   Physics of a Freely Falling Body. What is the physics behind a free-falling body? A body is in free-fall when it is accelerating at a constant rate under the force of gravity. This means that there are no other forces acting on the object to change its motion. The word “free” in “free fall” means that the only force acting on the falling object is gravity. There are no other forces to affect it. As a result, when an object falls freely, it fa...

What is Constant Acceleration in Physics | Mechanics

Image
  What is Constant Acceleration in Physics? In physics, a constant acceleration is a condition in which the velocity of an object is the same at any point in time. A particle's velocity changes uniformly at a constant rate. When the speed of a particle is t=10, it moves at -14 m/s and decreases to 6-2t m/s at t=2t. Its velocity is v(t)=2t m/s in the first second and 4 + 2t m/s at t=2.  What is Constant Acceleration in Physics Constant acceleration is also referred to as "constant velocity". It refers to the fact that an object's velocity changes the same amount every second. In physics, it's usually referred to as "constant" because the change in velocity is proportional to the mass of the object. As speeds get close to the speed of light, this effect becomes extremely large and is therefore the most difficult to calculate. In physics, an object moves northwards with a constant acceleration. This is the same principle that applies to any motion in a two-...

What Is Constant Velocity in Physics | Mechanics

Image
 What Is Constant Velocity in Physics? What is constant velocity in physics? A particle moves from its origin to a point with a constant speed. Its velocity is given by x(5) = 6 m/s. If the particle is traveling at a rate of 1.5 m/s, its velocity is constant. This means that the particle will remain the same speed for an extended period of time. In other words, a particle has a constant velocity. What Is Constant Velocity in Physics What is constant velocity in physics? A particle moves from point A to point B with a constant speed. If the velocity were constant, then the particle would travel to point B in an equal amount of time. Using this concept, the automobile will continue to move at a constant speed for an unchanging amount of time. Its constant speed would allow it to travel at a certain speed even when traveling in a curved path. A particle is moving from point A to point B at a constant rate. If it has a constant velocity of -1.75 m/s, the displacement is 50 metres. The ...

What is Average Acceleration in Physics | Mechanics

Image
  What is Average Acceleration in Physics? In physics, average acceleration refers to the rate at which the velocity of a moving body changes. It can be positive or negative. It can be zero. The average acceleration of a marble in a race would be 20 cm/s2. This figure is used to calculate the speed of an object over a period of time. Let's take an example: imagine a marble is traveling at zero meters per second. The acceleration of the marble is seven and a half meters per second squared. The acceleration of a runner in a race would be twenty-five centimeters per second.  What is Average Acceleration in Physics The average acceleration of a car in a straight line is 60 m/s. The final velocity of a space shuttle is 28,968 km/h. The acceleration of a car is measured in units of velocity. In physics, average acceleration is the change in velocity per unit of time. The unit for average a motion is distance squared. It can be written as a symbol that has bars to indicate average ac...

What is Instantaneous Acceleration in Physics | Mechanics

Image
  What is Instantaneous Acceleration in Physics? In physics, instantaneous acceleration is a change in velocity that occurs at a certain point in time. For instance, if a runner is moving at 10 km/h in a direction of due east, he or she can reverse direction and move westward. The speed is the same in both directions, but the magnitude of velocity is different. In this case, the runner has experienced an acceleration. What is Instantaneous Acceleration in Physics The term "instantaneous acceleration" is used to refer to the limit of average acceleration over a short interval of time. It is also known as the derivative of a quantity (such as v) with respect to time. It is the rate of change of velocity at a specific instant in time. In physics, the term "instantaneous" is used in the context of the calculation of the rate of velocity and time. The underlying definition of instantaneous acceleration is that it is an acceleration that occurs over a short interval of ti...

What is Acceleration in Physics | Mechanics

Image
  What is Acceleration in Physics? If you've ever driven a car, you've probably heard of acceleration. This is the change in speed that an object experiences when it is moved forward, backwards, or in any other direction. Likewise, if you've ever turned the steering wheel, you've experienced acceleration. The change in velocity will be measured by the inverse square of the time. If an object experiences an acceleration, it is moving faster than it was before. What is Acceleration in Physics In physics, acceleration is the rate at which the velocity of an object changes. If the velocity of an object is changing continuously, then the object is accelerating. This concept is commonly used to calculate the force needed to accelerate an object. In other words, the force needed to increase a body's velocity is equivalent to the acceleration. This process is called "velocity doubling." The same applies to the angular momentum. In physics, acceleration is a change...
