Forces

Question 1

Contact forces

Answer 1

-friction
-air resistance
-tension
-normal reaction

Question 2

Non-contact forces

Answer 2

-electrostatic
-magnetic
-gravitational

Question 3

Scale diagrams

Answer 3

A single force can be resolved into two component forces which are acting perpendicular to one another. Use a protractor to measure the angle and ALWAYS connect nose to tail

Question 4

Equilibrium scale diagrams

Answer 4

When forces are acting on an object in equilibrium, if we connect them together from nose to tail, they will form a closed shape
