Speed, Velocity, Acceleration

Front

What is the definition of speed?

Back

Speed is the rate at which an object covers distance.

Front

What is the definition of velocity?

Back

Velocity is the rate at which an object changes its position, including direction.

Front

What is acceleration?

Back

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

Front

What two factors does speed depend on?

Back

Speed depends on distance and time.

Front

Is a turtle crawling 34 cm/min an example of speed or velocity?

Back

This is an example of speed.

Front

What is an example of speed?

Back

A roller coaster traveling 10 meters per second.

Front

What is the difference between speed and velocity?

Back

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

Front

What happens to acceleration when an object speeds up?

Back

When an object speeds up, its acceleration is positive.

Front

What happens to acceleration when an object slows down?

Back

When an object slows down, its acceleration is negative (deceleration).

Front

Can an object have a constant speed but changing velocity?

Back

Yes, if the object is changing direction while maintaining the same speed.
