Did you know?

 

The mass of an object is a measure of its reluctance to change motion – the extent to which it impedes acceleration.

 

  • Primary objective: draw free body diagrams and find the unknown forces on various objects, including objects being pushed at an angle, objects on inclines, and objects in static equilibrium; differentiate between actual and apparent weight
