FORCES

Force measured in Newtons with a Newtonmeter.

Types of force include GRAVITY, FRICTION, UPTHRUST, DRAG and WEIGHT (as well as PUSH, PULL, TWIST and TEAR).

Our revision experiment involved the weighing of masses in air and then in water.

Objects under water experience GRAVITY and UPTHRUST.

If forces on an object are balanced then the object will either be stationary or will be travelling at a steady speed in a straight line.

TO MOVE FROM LEVEL 4 TO LEVEL 5, YOU MUST USE THE WORD 'BECAUSE'.
