Newtons Laws

Evaluating the forces involved in motion

Mechanical interaction between two objects Results of contact (like friction) or can act at a distance (gravity) Measured in newtons (N)

Motion of the body/object due to the sum of forces acting on it Ex trampoline jumper The greater the force the higher they go

Force acting between all objects with mass

Amount of material in object/body

Effect of the force of gravity on mass

Objects at rest will stay at rest and objects in motion will stay in motion unless acted upon by another force

Tendency of an object to resist changing motion

F=ma (force=mass•acceleration) The acceleration of an object in proportional to and in the same direction as the force is applied

For every action there is an equal and opposite reaction

Height of center of mass relative to supporting surface - lower=more stable Size of base - larger=more stability Size of mass - larger=more stability

Objects often have multiple forces acting on them simultaneously The sum of these forces determine resultant motion
