Forces Flashcards
1
Q
Contact forces
A
-friction
-air resistance
-tension
-normal reaction
2
Q
Non-contact forces
A
-electrostatic
-magnetic
-gravitational
3
Q
Scale diagrams
A
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
4
Q
Equilibrium scale diagrams
A
When forces are acting on an object in equilibrium, if we connect them together from nose to tail, they will form a closed shape
