Forces and elasticity

Loading...

Description

When two or more forces are applied to an object, its shape can change; this video looks at the physics and (mathematics) which describe how this can happen.  It also includes material which is relevant to the required practical activity for this part of the course which is on investigating the relationship between the force applied to a spring and its extension.

Key Words

elastic potential energy, work done, force, tension, spring, extension, Hooke's law, limit of proportionality, elastic deformation, inelastic deformation, compression, linear, non-linear, spring constant
