Aims…
1.11 describe the effects of forces between bodies such as changes in speed, shape or direction
1.12 identify different types of force such as gravitational or electrostatic
1.13 understand how vector quantities differ from scalar quantities
1.14 understand that force is a vector quantity
1.15 calculate the resultant force of forces that act along a line
1.16 know that friction is a force that opposes motion
——–
1.22 practical: investigate how extension varies with applied force for helical springs, metal wires and rubber bands
1.23 know that the initial linear region of a force-extension graph is associated with Hooke’s law
1.24 describe elastic behaviour as the ability of a material to recover its original shape after the forces causing deformation have been removed.

In this video, we look at what is meant by contact and non-contact forces. We then look at examples of these ...forces.
