Free practice on Forces for Class 6, following the Cameroon primary school curriculum (English subsystem). Every answer is explained, so a parent who is not sure of the answer can still help.
Associating forces with different activities, lifting a heavy load mainly involves a pulling or pushing force applied by muscles or a machine. A tug-of-war rope being pulled from both ends experiences tension force.
Tug-of-war rope — tension vs Squeezing clay — compression
Understanding forces like tension and compression is useful in construction, because it helps engineers build structures that can safely bear the forces acting on them.
