Front

Define velocity.

Back

The speed of an object in a particular direction.

Front

What distinguishes velocity from speed?

Back

Velocity has a direction associated with it, while speed has no specific direction.

Front

What is the formula for velocity?

Back

Velocity = Speed + direction.

Front

Front

What is acceleration?

Back

The rate of change of velocity over time.

Front

What is the unit of acceleration?

Back

m/s² (meters per second squared).

Front

How does acceleration relate to velocity?

Back

Acceleration indicates how quickly an object’s velocity is changing.

Front

What is the difference between uniform and non-uniform acceleration?

Back

Uniform acceleration means the rate of change of velocity is constant, while non-uniform acceleration means it varies.

Front

What is the formula for calculating acceleration?

Back

Acceleration = (Final velocity - Initial velocity) / time.
