|
Deceleration:
|
Decrease in velocity (Negative Acceleration) and can cause a change in direction
|
|
Speed:
|
Distance traveled by an object per unit of time
Speed= Distance Traveled/Time
|
|
Displacement:
|
As the distance that the object is from some starting point, and it is measured in units
|
|
Velocity:
|
Speed in a given direction
|
|
Acceleration:
|
Rate of change in velocity
Acceleration= Final Velocity-Original Velocity/Time
|
|
|
Newton(N):
is the unit that represents a force that accelerates a mass of 1 kilogram 1 meter per second.
|
|
Momentum:
|
An object traveling at a specific velocity. All moving objects have momentum
Momentum= Mass x Velocity
|
|
Impulse:
|
Change in objects momentum
|
|
Newton’s First Law:
|
Objects in motion tend to stay in motion, and objects at rest tend to stay at rest.
|
|
Newton’s Second Law:(Cont)
|
Relationship between force, mass, and acceleration. It states that the force applied
|
|
Force=Mass x Acceleration
|
On an object equals the mass of the object times the acceleration of the object
|
|
Friction:
(Box being pushed along the floor)
|
Force is exerted on an object along a surface, or an object has a velocity along the surface, and the 2 surfaces touch.
|
|
Gravity:
|
Force of attraction between all objects in the universe
|
|
Torque:
|
The ability of a force that is applied perpendicularly to rotate an object around an axis (Ball on string)
|
|
Lever Arm:
|
The distance from the axis of rotation to the point where the force is exerted
