newtons laws Flashcards
force
a push or pull exerted to change the motion on object.
motion
a change in position over time.
net force
The combination of all the forces acting on an object.
speed
Distance traveled per rate of time. S=d+T
Velocity
The speed and direction of an object.
Acceleration
The rate that velocity changes over time.
newton’s first law
An object at rest will remain at rest and and an object in motion will stay in motion unless acted upon by another force.
newton’s 2nd law
Force= mass x acceleration
Newton’s third law
For every action there is an equal but opposite reaction.
Inertia
THe tendancey of an objacet to resist being moved or if the object is moving.
Friction
A force that resists motion.
Mass
The amount of matter in an object.
Gravity
An attractive force that exists between all objects that have mass.
