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

What does a flat line on a distance-time graph indicate?

Back

A flat line indicates that the object is not moving.

Front

What does a steeper slope on a distance-time graph represent?

Back

A steeper slope indicates a higher speed.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object.

Front

What force pulls objects towards the Earth?

Back

Gravity pulls objects towards the Earth.

Front

What does a downward slope on a distance-time graph indicate?

Back

A downward slope indicates that the object is returning to the starting point.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What does a curved line on a distance-time graph represent?

Back

A curved line indicates that the object is accelerating or decelerating.

Front

What is the unit of speed in the metric system?

Back

The unit of speed in the metric system is meters per second (m/s).

Front

What is the difference between constant speed and variable speed?

Back

Constant speed means the speed does not change, while variable speed means the speed changes over time.
