Motion and speed

Front

What is speed?

Back

Speed is how much distance is covered over a period of time.

Front

Which of the following is a unit of speed?

Back

m/s (meters per second)

Front

What is the formula used to calculate time if you know the speed and the distance?

Back

T = D/S (Time = Distance / Speed)

Front

What does acceleration mean in the context of motion?

Back

Acceleration refers to the change in velocity of an object, which can occur when speeding up, slowing down, or changing direction.

Front

What is motion?

Back

Motion is an object's change in position relative to a reference point.

Front

What is the relationship between distance, speed, and time?

Back

Distance = Speed x Time.

Front

What happens to an object's speed when it accelerates?

Back

The object's speed increases.

Front

What is a reference point in motion?

Back

A reference point is a stationary object used to determine if another object is in motion.

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

How can you calculate speed?

Back

Speed = Distance / Time.
