Speed, Velocity, Acceleration

Front

What is speed?

Back

Speed refers to how fast an object is moving, measured as distance traveled over time.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can involve speeding up, slowing down, or changing direction.

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

Give an example of speed.

Back

A roller coaster is traveling 10 meters per second.

Front

Give an example of velocity.

Back

A train is traveling North at 220 km/hr.

Front

What does it mean if an object is in constant motion?

Back

If an object is in constant motion, it means it is moving at a constant speed in a straight line without changing its velocity.

Front

What is an example of acceleration?

Back

A car speeding up from a stoplight is an example of acceleration.

Front

What is NOT an example of acceleration?

Back

An object is in constant motion.

Front

How can direction affect velocity?

Back

Velocity includes direction; changing direction while maintaining speed results in a change in velocity.

Front

What happens to an object's speed if it accelerates negatively?

Back

If an object accelerates negatively, it slows down.
