Speed and Velocity Practice

Front

What is speed?

Back

Speed is the distance traveled per unit of time, typically measured in meters per second (m/s).

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction, also measured in meters per second (m/s).

Front

How do you calculate speed?

Back

Speed = Distance / Time.

Front

If a sound wave travels 200 meters in 5 seconds, what is its speed?

Back

40 m/s.

Front

What does a constant velocity indicate about an object's motion?

Back

It indicates that the object is moving at the same speed and in the same direction over time.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity per unit of time, measured in meters per second squared (m/s²).

Front

If a ball is dropped, what is its velocity after 3 seconds under ideal conditions?

Back

29.4 m/s.

Front

What happens to the velocity of an object if it is accelerating?

Back

The velocity of the object increases over time.

Front

How do you calculate acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time.

Front

If a car starts from rest and reaches a final velocity of 20 m/s in 4 seconds, what is its acceleration?

Back

5 m/s².
