Forces and motion

13 cards·by Kayla

Force

Push or pull that acts on a object

Net force

Overall force acting on a object after all the forces are combined.

Friction

Force that opposes the motion of the objects that touch as they past eachother

Static friction

friction force that acts on objects that are not moving

Sliding friction

Force that opposes the direction of motion of an object as it slides over a surface

Rolling friction

friction force that acts on rolling objects

Fluid friction

opposes the motion of an object through fluid

Gravity

force that acts between any two masses

Terminal Velocity

constant velocity of a falling object when the force of air resistance equals the force of gravity

projectile motion

motion of a falling force after is has been given a initial forward velocity

Inertia

tendency of an object to resist a change in its motion

Mass

measure of the inertia of an object and depends on the amount of matter the object contains

Weight

Force of gravity acting on a object
