Force — definition?
An external influence that pushes or pulls objects.
Elastic vs plastic deformation?
Elastic is temporary; plastic is permanent shape change.
Force — definition?
Push or pull acting on an object.
Tensile vs compressive force — difference?
Pulling versus pushing actions.
Force effects — types?
Motion change and shape deformation.
Elastic deformation — description?
Temporary shape change, reverts after force removed.
Plastic deformation — description?
Permanent shape change, remains after force removed.
Force magnitude — influence?
Larger force causes bigger effects.
Visible force — example?
Friction or contact force observed directly.
