What is friction?

Back

Friction is a force that opposes the motion of an object, acting opposite to the direction of the applied force.

Front

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

Back

A horizontal line indicates that the object is stopped, as there is no change in distance over time.

Front

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

Back

A steeper line indicates greater speed, meaning the object is moving faster.

Front

What does a downward sloping line on a distance-time graph indicate?

Back

A downward sloping line indicates that the object is slowing down.

Front

What does an upward sloping line on a distance-time graph indicate?

Back

An upward sloping line indicates that the object is speeding up.

Front

What is the definition of speed?

Back

Speed is the distance traveled per unit of time, typically measured in meters per second (m/s).

Front

What is constant speed?

Back

Constant speed means that an object covers equal distances in equal intervals of time, without speeding up or slowing down.

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

What does a speed-time graph show?

Back

A speed-time graph shows how the speed of an object changes over time.

Front

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

Back

A flat line indicates that the object is moving at a constant speed.
