New cards
Force
a push or pull on an object
2
New cards
Gravity
A force of attraction between objects that is due to their masses.
3
New cards
Speed
How fast an object moves. Distance/time
4
New cards
Velocity
the speed and direction of a moving object
5
New cards
Acceleration
The rate at which velocity changes
6
New cards
Friction
A force that opposes motion between two surfaces that are in contact
7
New cards
potential energy
Energy that is stored and held in readiness
8
New cards
kinetic energy
the energy an object has due to its motion
9
New cards
G-force
gravitational force. It is equal to the force exerted on an object by the earths gravity at sea level.
10
New cards
Centripetal
The force that allows objects to follow a curved path.
11
New cards
Inertia
The tendency of an object to resist a change in motion.
12
New cards
weightlessness
an object's apparent weight of zero that results when there are no contact forces pushing up on the object

What is equal to the force of gravitational acceleration?
22
New cards
Weight
the force of gravity on an object
23
New cards
Newton's 1st Law
An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.
24
New cards
Newton's 2nd Law of Motion
The acceleration of an object depends on the mass of the object and the amount of force applied.
25
New cards
Newton's 3rd Law
For every action there is an equal and opposite reaction
