Acceleration and Velocity Concepts

Front

What is acceleration?

Back

Acceleration is the rate at which an object's velocity changes over time.

Front

What does negative acceleration indicate?

Back

Negative acceleration indicates that an object is slowing down.

Front

What does positive acceleration indicate?

Back

Positive acceleration indicates that an object is speeding up.

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction.

Front

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

Back

The acceleration is zero.

Front

What happens to the velocity of an object when it changes direction?

Back

The velocity changes because velocity includes direction.

Front

How do you calculate acceleration?

Back

Acceleration = (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

If a car speeds up from 20 m/s to 50 m/s in 10 seconds, what is its acceleration?

Back

Acceleration = (50 m/s - 20 m/s) / 10 s = 3 m/s².

Front

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

Back

It means the object is moving at the same speed and in the same direction.
