- Forces
- Vector and Scalar Quantities
- vector quantities have a magnitude and direction.
- e.g. force, velocity, displacement
- scalar quantites have magnitude and no direction
- e.g. speed, distance, mass
- vector quantities have a magnitude and direction.
- Contact and Non-Contact Forces
- a contact force is when two objects have to be touching for a force to act
- e.g. friction, air resistance
- a non contact force is when objects don't need to be touching for the force to act
- e.g. magnetic force, gravitational force
- a contact force is when two objects have to be touching for a force to act
