A vector quantity.
Description of object motion
The the study of motion of objects and the forces that act upon them.
Forces acting on objects
A vector quantity
Acceleration where velocity changes by a constant amount
EX: 0 m/s² -> 10 m/s² -> 20 m/s² -> 30 m/s²
Being solely under the force of gravity.
This may include air resistance
Description of objects at rest
A contact force that always exerts itself perpendicular to an object acting on a surface.
A force that exerts itself parallel and opposite an applied force. It resists applied force in the opposite direction.
Force that results from pulling on a rope.
Forces that occur as a result of direct physical contact between objects.
Force that results from an object exerting a force over another object.
A simple diagram that shows the objects and forces that act on them and in what direction and at what angle.
How much matter is in an object. This is static anywhere in the universe. This is measured in kg and is a scalar quantity.
A space in which air has been almost or completely removed entirely.
Forces that affect objects without being in direct physical contact with the object. An example would be gravity, magnetic, or electrical forces.
The force exerted on a mass by gravity. It varies depending on where you are in the universe. This is measured in Newtons and is a vector quantity
