Q

Friction

A

Force opposing motion which is caused by the interaction of surfaces moving over one another. It is called ‘drag’ if one is a fluid.

Q

metres per second

A

A unit of speed.

17
Q

Newton

A

Unit for measuring forces (N).

18
Q

Newtonmeter

A

A piece of equipment used to measure weight in newtons.

19
Q

Non- contact force

A

Force that acts without direct contact, e.g., magnetism

20
Q

pull

A

A type of force.

21
Q

push

A

A type of force.

22
Q

relative motion

A

Different observers judge speeds differently if they are in motion too, so an object’s speed is relative to the observer’s speed.

23
Q

resistive force

A

Any force that acts to slow down a moving object.

24
Q

resultant force

A

Single force that can replace all the forces acting on an object and have the same effect. Calculated by taking the small force away from the bigger force acting in opposite directions.

25
Q

speed

A

How much distance is covered in a given time.

26
Q

unbalanced forces

A

Opposing forces on an object are not equal.

27
Q

weight

A

The force of gravity due to the Earth or other planets/ moons on an object with mass (N).
