## What is an object moving at a constant velocity?

Motion with Constant Velocity: When an object is moving with constant velocity, it does not change direction nor speed and therefore is represented as a straight line when graphed as distance over time.

## When a body travels with constant velocity then its acceleration is zero True or false?

An object moving at uniform or constant velocity has zero acceleration because there is no change in velocity. Q. If a body is moving with uniform velocity in a given direction its acceleration will be zero.

## When a body is moving at a constant velocity?

Acceleration is zero for a body moving with constant velocity. The body moves with uniform velocity.

## Is a body moving with a constant velocity will have zero acceleration True or false?

In such cases, the acceleration is due to the change in direction, not the change in speed. The correct statement would be: A body moving with a constant velocity in a straight line will have zero acceleration.

## Can constant velocity be zero?

Derivative of velocity with respect to time is acceleration. That means if accelerations is zero, velocity must be constant. Now that constant could be anything like it could be 5 m/s . Also if the velocity is 0(which is itself a constant) also indicates that acceleration is zero.

## What is an example of an object with constant velocity?

Answer to Essential Question 2.3: Some examples of constant velocity (or at least almost- constant velocity) motion include (among many others): • A car traveling at constant speed without changing direction. A hockey puck sliding across ice.

## Can a body moving with constant velocity have acceleration?

Since speed is equal to the magnitude of the velocity vector, it will also be constant. Again, since the acceleration is the rate of change of velocity of a body with time, if the velocity is constant, the acceleration of the body will be zero.

## When velocity is zero is speed zero?

If speed is zero, then its velocity must also be zero. If average velocity is zero, then its average speed need not be zero. If speed is constant, then its velocity must also be constant. If velocity is constant, then its speed must also be constant.

## Can a body have constant velocity but zero acceleration?

If the acceleration of a body is not zero, then its velocity can be constant. A body having zero velocity will necessarily have zero acceleration.

## What is the SI unit of retardation?

Answer: The SI unit of Retardation (m/s²) meter per second squared. According to the definition, Acceleration can be defined as the rate of change of the velocity of any object. Retardation is the total opposite of acceleration i.e., negative acceleration.

## Is friction a negative force?

Answer and Explanation: Frictional force is a negative force. This means that it operates against the force performing the positive work to move an object across the surface of another object.

## What is the difference between speed and velocity?

Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object’s movement. Put another way, speed is a scalar value, while velocity is a vector.
