Speed, Velocity, Acceleration

Front

What is speed?

Back

Speed is the distance traveled per unit of time. It is a scalar quantity and does not include direction.

Front

What is velocity?

Back

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

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 are the two factors that determine speed?

Back

Speed depends on distance and time.

Front

What are the two factors that determine velocity?

Back

Velocity depends on speed and direction.

Front

True or False: An object moving at a constant speed is accelerating.

Back

False. An object moving at a constant speed is not accelerating unless its direction changes.

Front

What is an example of acceleration?

Back

An example of acceleration is a car speeding up from a stop or a dancer changing direction while spinning.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

What happens to acceleration when an object is at rest?

Back

When an object is at rest and not changing its speed or direction, its acceleration is zero.

Front

Which of the following is NOT an example of acceleration?

Back

An object in constant motion is NOT an example of acceleration.
