|
Motion
|
The action or process of moving or being moved.
|
|
|
Mass
|
A coherent typically large body of matter with no definite shape.
|
|
|
Force
|
Strength or energy as an attribute of physical action or movement.
|
|
|
Balanced Forces
|
Forces are balanced when the forces pushing or pulling an object in one direction are the same size as the forces acting in the opposite direction.
|
|
|
Unbalanced Forces
|
In physics, tension is the pulling force exerted by a string, cable, chain, or similar solid object on another object
|
|
|
Work
|
In physics, a force is said to do work when it acts on a body, like whenever a batter hits a ball.
|
|
|
Speed
|
the rate at which someone or something is able to move or operate.
|
|
|
Distance
|
The amount of space between two objects.
|
|
|
Time
|
measure the time taken by a process or activity, or a person doing it, example would be that the speed of an object.
|
|
|
Velocity
|
The speed of something in a given direction.
|
|
|
Acceleration
|
Increase in the rate or speed or something.
|
|
|
Deceleration
|
A decrease in the rate of change;"The deceleration of the arms race".
|
|
|
Energy
|
The strength and vitality required for sustained physical or mental activity.
|
|
|
Newton's Law of Inertia
|
Newton's first law states that a body at rest will remain at rest, and a body in motion will remain in motion with a constant velocity, unless acted upon by a force. This law is also called the law of inertia.
|
|
|
Newton's Law of force and acceleration
|
The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object).
|
|
|
Newton's Law of action-reaction
|
This means that for every force there is a reaction force that is equal in size, but opposite in direction. That is to say that whenever an object pushes another object it gets pushed back in the opposite direction equally hard.
|
|
|
Displacement
|
the moving of something from its place or position.
|
|
|
Friction
|
The resistance that one surface or object encounters when moving over other
|
|
|
Free Fall
|
Move under the force of gravity only; fall rapidly.
|
|
|
Momentum
|
The impetus gained by a moving body.
|
|
|
Projectile
|
Relating to a projectile missile or object.
|
|
|
Period
|
Is the number of occurrences of a repeating event per unit time. It is also referred to as temporal frequency, which emphasizes the contrast to spatial frequency and angular frequency.
|
|
|
Frequency
|
the rate at which a vibration occurs that constitutes a wave, either in a material (as in sound waves), or in an electromagnetic field (as in radio waves and light), usually measured per second.
|
|
|
Centripetal Force
|
A force that acts on a body moving in a circular path and is directed toward the center around which the body is moving.
|
|
|
Centripetal Acceleration
|
The acceleration toward the center that holds a satellite in elliptical orbit
|
|
|
Newton (SI unit not Sir Newton)
|
Those two people created the law of law force and acceleration, Law of action reaction.
|
|
|
Inertia
|
a property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force
|
