Acceleration

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can be positive (speeding up) or negative (slowing down).

Front

How is acceleration calculated?

Back

Acceleration (a) is calculated using the formula: a = (final velocity - initial velocity) / time.

Front

What is the unit of acceleration?

Back

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

Front

What does a positive acceleration indicate?

Back

A positive acceleration indicates that an object is speeding up.

Front

What does a negative acceleration indicate?

Back

A negative acceleration indicates that an object is slowing down.

Front

If an object is moving at a constant speed, what is its acceleration?

Back

The acceleration is 0 m/s² because there is no change in velocity.

Front

What is the acceleration of an object that goes from 10 m/s to 10 m/s in 5 seconds?

Back

The acceleration is 0 m/s² because there is no change in velocity.

Front

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

Back

The acceleration of an object in free fall is approximately 9.81 m/s² downward due to gravity.

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 is uniform acceleration?

Back

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