forces
scaler vector - only has magnitude and size
eg- mass, energy, distance, speed, density
vector quantities - both have magnitude
eg- force, velocity, momentum
contact forces - two objects physically touching
eg- friction, air resistance
non contact - physically seperated
eg- electrostatic, magnetic, gravatitional force
oppisite magnet poles- attract
like magnet poles- repel
gravity
weight = mass × gravitational field strength
work done = force × distance
1 joule= 1 newton metre
- elastic deformation is reversed when the force is removed
- inelastic a permanent change…
