This collection of problem sets and problems target student ability to use vector principles and operations, kinematic equations, and Newton's Laws to solve physics word problems associated with objects moving in two dimensions.
Practice solving for net force, using Newtons second law (F=ma), and relating F=ma to the acceleration equations. In these practice problems we will either use F=ma or our 1D motion acceleration equations to solve force problems.

Learn how to solve various force problems involving tension, friction, equilibrium, and Newton's second law. See the problems, equations, background reading, and answers with hints on this web page.
This collection of problem sets and problems target student ability to use Newton's laws and associated mathematics to solve physics word problems.
About 20 different forces are briefly described. The use of free body diagrams is explained. Newton's 1st law of motion is stated and used to define force.
This section of The Physics Hypertextbook is a gathering place for problems where the forces on a moving object do not always point in a convenient direction.
