Front

Changing the speed and changing the direction of your bicycle are both examples of _____________.

Back

acceleration

Front

What is the difference between speed and velocity?

Back

Speed is the distance traveled per unit of time, while velocity includes direction.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity over time.

Front

If an object is moving at a constant speed in a circular path, is it accelerating?

Back

Yes, because its direction is changing.

Front

What happens when two forces of equal magnitude act in opposite directions?

Back

They create a balanced force and the object does not move.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time

Front

What unit is commonly used to measure speed?

Back

meters per second (m/s) or kilometers per hour (km/h)
