## What is uniform motion of a car in circular motion?

EXPLANATION: Here the direction of the velocity of the particle (Car) is changing continuously but the magnitude is the constant. So, there will not any tangential acceleration but there will always be a centripetal acceleration of constant magnitude but of fixed direction toward the center of rotation.

## When a car is executing a uniform circular motion?

Answer: If a car is executing uniform circular motion, its centripetal acceleration is a constant vector pointing towards the center of the circle and its magnitude is given by the formula a = v^2 / r, where a is the centripetal acceleration, v is the velocity of the car and r is the radius of the circle.

## What is the acceleration of a car in uniform circular motion?

In uniform linear motion, the velocity is constant and hence acceleration is zero. While in a uniform circular motion, velocity is not constant due to continuous change in direction & thus it is not a uniform motion. In uniform circular motion, acceleration is called Centripetal acceleration.

## Why an object is moving in a uniform circular motion?

But the actual case is that the object is in circular motion because of the centripetal force otherwise the Newton’s First law applies i.e., the object can’t change its direction until an external force is applied.

## What is an example of a uniform circular motion?

Uniform Circular Motion Examples Motion of artificial satellites around the earth is an example of uniform circular motion. The gravitational force from the earth makes the satellites stay in the circular orbit around the earth. The motion of electrons around its nucleus. The motion of blades of the windmills.

## What are the five examples of uniform circular motion?

- motion of electrons around nucleus.
- motion artificial satellite around the earth at constant altitude.
- Walking in circular path with constant speed.
- Spinning of a top in friction less surface.
- Rotation of fan blades at constant speed.

## Is the motion of the car uniform or non uniform?

Example of Uniform Motion: If the speed of a car is 10 m/s, it means that the car covers 10 meters in one second. The speed is constant every second. Movement of blades of a ceiling fan.

## Is acceleration 0 in uniform circular motion?

In uniform circular motion, acceleration is zero.

## What changes continuously in uniform circular motion?

(b) When a body moves in a circular path, then its direction of motion keeps changing continuously. Hence, velocity is changed continuously.

## Is speed constant in uniform circular motion?

In uniform circular motion speed is constant, but the direction is changing at each point of motion. Hence velocity varies continously. Therefore, uniform circular motion is also known as uniform accelerated motion.

## Why is circular motion non uniform?

Non-uniform circular motion is a circular motion when the speed of the body doesn’t remain constant. The body has both normal as well as tangential acceleration.

## How do you explain that an object is in uniform circular?

(A) An object is said to be in uniform circular motion if it is moving with a constant speed on the circumference of a circular track. Although the speed of the object in the uniform circular motion is constant, the velocity of the object is not constant.

## When a car travels along a circular path at a constant speed does it have uniform motion?

Does it have uniform motion? Yes. If a car travels in a circular path with constant speed, its motion is called uniform circular motion.

## When a car moves around a circular track with uniform speed is in non uniform motion or uniform motion?

When a body moves in circular path with uniform speed, it’s motion is called uniform circular motion.

## When a car goes around a circular curve the force acting on the car is a frictional force?

When a car is turning along a circular path with a constant speed, it requires a centripetal force to keep it moving along that path. This force is a frictional force which points toward the center of the circle which the car traces.

## What direction does the centripetal acceleration point when a car is exhibiting uniform circular motion?

The direction of a centripetal force is toward the center of curvature, the same as the direction of centripetal acceleration. According to Newton’s second law of motion, net force is mass times acceleration: net F = ma. For uniform circular motion, the acceleration is the centripetal acceleration—a = ac.
