Newton's laws of motion vocabulary Flashcards
1
Q
Force
A
A push or a pull exerted on an object in order to change the motion of the object.
2
Q
net force
A
The combination of all the forces acting on an object.
3
Q
speed
A
Distance traveled per rate of time.
Speed = distance/time
4
Q
velocity
A
The speed and direction of an object.
5
Q
acceleration
A
The rate at which velocity changes over time.
6
Q
Newton’s first law
A
An object at rest will remain at rest and an object in motion will remain in motion unless acted upon by an outside force.
7
Q
Newton’s second law
A
Force = mass x acceleration
8
Q
Newton’s third law
A
For every action there is an equal but opposite reaction.
9
Q
friction
A
A force that resists motion
10
Q
mass
A
The amount of matter in an object.
11
Q
gravity
A
An attractive force that exists between all objects that have mass.
