A
The total number of Newton's Laws of Motion
Three (3)
A measure of the space between two positions
Distance
Energy of motion
Kinetic energy
A pulling force exerted on an object by a rope
Tension force
A push or a pull on an object
Force
Measure of how fast an object moves
Speed
Stored energy
Potential energy
Devices that are designed to make work easier
Machines
A parked car will remain at rest, unless acted on by an outside force.
This is an example of Newton's ___ Law
First (1st)
An object's net change in position in both distance and direction
Displacement
The tendency of a body to keep moving once it is set in motion
Inertia
Force that either slows a moving object or prevents a non-moving object from being moved
Friction
In the formula F = ma
F represents the net force, m represents the object's mass, and a represents the object's acceleration.
This is Newton's ___ Law
Second, (2nd)
An object's total displacement divided by the amount of time the object is in motion
Velocity
During interactions, energy may change from one form to another, but no energy is lost. The total amount of energy present remains constant.
Law of Conservation of Energy
The amount by which a machine makes work easier. It is calculated by dividing output force by input force.
Mechanical advantage
When a rocket is launched, the force of the gases coming out of the bottom of the rocket forces the shuttle in the opposite direction, upward from the launch pad.
This is an example of Newton's ___ Law
Third, (3rd)
The change in an object's velocity over time
Acceleration
The product of mass and velocity of a body, and the measure of the quantity of motion of a body
Momentum
When an object rests or pushes on a surface, the surface exerts a push on it directed perpendicular to the surface
Normal force
