Force
A push or pull that one object can exert on another, causing the object to change in position (move/accelerate)
f=ma
Formula for force (force = mass x acceleration)
kg x m/s² (Newton)
SI unit for force
Balanced Force
when equal forces in opposite directions are applied to an object, resulting in no change in motion as they cancel out
Unbalanced Force
When a force is applied to an object and is not balanced by another force, resulting in a change in motion / acceleration
Net Force
The result (sum) of all forces acting on an object
Inertia
-The tendency of an object to resist a change in motion
-A property of matter (mass)
-The greater the mass of an object, the greater its resistance to a change in motion
Newton’s 1st Law of Motion
The tendancy of an object to resist a change in motion unless acted on by an unbalanced force.
Newton’s 2nd Law of Motion
An object will accelerate in the direction of the net force
Law of Universal Gravitation
The attractive force between any two masses that is greater when the objects are closer together and have more mass
