Newton's First Law of Motion
An object in motion will stay in motion forever unless it is acted on by an unbalanced force and an object at rest will stay at rest unless an unbalanced force acts upon it as well.
Newton's Second Law of Motion
acceleration depends on the object's mass and on the net force on the object
Newton's third law of motion
states that whenever one object exerts force on a second object, the second object exerts an equal and opposite force on the first object
Terminal Velocity
Greatest velocity an object can reach is called _______.
Push and Pull
A force is a push or pull on an object. The difference between a push and a pull is that a push is when you exert a force on an object and a pul…
Projectile Motion
2D Motion in which the object moves at a constant velocity in one direction and accelerates in another
inertia
_______ is the property of an object that leads it to resist any change in motion
gravity
(physics) the force of attraction between all masses in the universe
momentum
(p) vector quantity describing the quantity of motion or inertia in motion. Recognizes that both mass and velocity have a part in the motion of an object and is proportional to both (is zero …
Centripetal Force
A force directed towards the center of a circle that causes an object to follow a circular path
Newtons
This is the unit of measurement for force.
net force
Acceleration depends on the
air resistance
Fluid friction acting on an object moving through the air.
friction
a contact force; type of force between two touching surfaces
Balanced and Unbalanced Forces
These are the forces that are equal and opposite in direction.
acceleration
(physics) a rate of change of velocity
Orbit
Is a curved path that objects follow when influenced by large gravitational bodies such as planets or stars.
force
(interactions between two objects)
Action and Reaction Force
This is the force that exerts a force on another object. This is the force that acts in an opposite direction to an action force.
conservation of momentum
the total momentum of a system of objects does not change, as long as no outside forces are acting on that system.
