Unbalanced forces
In physics, a force is any interaction that, when unopposed, will change the motion of an object
free-body diagrams
In physics a free body diagram is a graphical illustration used to visualize the applied forces, movements, and resulting reactions on a body in a steady state condition
Free fall
In Newtonian physics, free fall is any motion of a body where gravity is the only force acting upon it
terminal velocity
Terminal velocity is the highest velocity attainable by an object as it falls through a fluid
lever
A lever is a machine consisting of a beam or rigid rod pivoted at a fixed hinge, or fulcrum
pulley
A pulley is a wheel on an axle or shaft that is designed to support movement and change of direction of a taught cable, rope or belt along its circumference
