motion: a change in position, or location of a place or object, over a certain amount of time
force: a push or pull on an object
Newtons 1st law
Newtons 2nd law
Newtons 3rd law
An object at rest stays at rest, and an object in motion stays in motion at a constant velocity unless acted on by an unbalanced force
The greater the mass and acceleration of an object, the greater the resulting force.
For every action, there is an equal and opposite reaction
distance
how much ground or space is covered by an object
displacement
difference between an object’s final position and its starting position
speed
the rate at which an object moves
velocity
speed in a given direction
acceleration
occurs when something is speeding up, slowing down, or changing direction
momentum
a quantity defined as the product of the mass and the velocity of an object
contact forces
non-contact forces
applied: force exerted by a person on an object
normal: force exerted upon an object in contact with another stable object
friction: resistance to movement against another object
air resistance: also known as drag, friction due to air particles, opposes motion of an object as it moves through the air, more noticeable on faster-moving objects
tension: pulling force by string, rope, or chain
spring: force exerted by a compressed or stretched spring upon any object attached to it
