Force: A push or pull on an object. Giving the object energy
to work or change.
gravity, electromagnetic, nuclear, air pressure, thrust, normal,drag
components: 1) magnitude/strength
f=m*a force equals mass
Newton (N)- 1kg/m/s/s
ability to do work or cause change.
(physical work) when force makes something move.
Forces: two or more forces that cancel each other out.
not cause change of object’s motion.
force is zero.
Forces: two or more forces that are not equal.
Causes the object to accelerate.
force is not zero.
Force: sum of forces upon an object (what’s left).
arrow to show force and amount of force upon object by
Friction: A force that slows motion, or prevent motion.
rubbing between two surfaces creating a resistance to the object in
of Friction: static, sliding, rolling, air
Inertia: resistance to change. How easy or hard to change
Velocity: rate of change of position/displacement
Mass: measurement of matter, space things take up. (kg)
Motion: change in position of object. The
distance object moved from original/reference point.
