Acceleration

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time.

Front

What is the unit of acceleration?

Back

The unit of acceleration is meters per second squared (m/s²).

Front

What does it mean when an object has a constant velocity?

Back

An object has a constant velocity when it is moving at the same speed in a straight line without changing direction.

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) = (Final Velocity (v) - Initial Velocity (u)) / Time (t).

Front

If a car is moving at a constant speed, is it accelerating?

Back

No, a car moving at a constant speed is not accelerating.

Front

What does a negative acceleration indicate?

Back

A negative acceleration indicates that an object is slowing down.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What happens to the acceleration of an object in free fall?

Back

In free fall, the acceleration of an object is equal to the acceleration due to gravity, approximately 9.81 m/s² downward.

Front

What is uniform acceleration?

Back

Uniform acceleration occurs when an object's acceleration is constant over time.

Front

How does friction affect acceleration?

Back

Friction opposes motion and can reduce the acceleration of an object.
