|
Momentum
|
An object traveling at a specific velocity has a qauntity. (all moving objects)
|
|
Conservation of momentum
|
The total momentum of an isolated system is always constant. When two objects collide, they transfer energy, it is not lost
|
|
Newton's First Law
|
Inertia, which states that objects in motion tend to stay in motion, and objects at rest tend to stay at rest. Resists any change in motion.
|
|
Newton's Second Law
|
Describes the relationship between force, mass, and acceleration.States that the force applied on an object equals the mass of the object times the acceleration of the object.F=ma (force= mass * acceleration)
|
|
Newton (N)
|
The unit that represents a force that accelerates a mass of 1 Kilogram 1meter per second.
|
|
Joule
|
Is the unit of energy equal to the work done by a force of one newton acting over a distance of one meter.
|
|
Friction
|
Is the force that opposes the relative motion or tendency of such motion of two surfaces in contact.
|
|
Gravity
|
The force of attraction between all masses in the universe
|
|
Weight
|
Is the force exerted upon an object by virtue of its position in a gravitational field
|
|
Lever-arm
|
The distance from the axis of rotation to the point where the force is exerted
|
|
Torque
|
The ability of a force that is applied perpendicularly to rotate an object around and axis, such as a ball on a string,
|
|
Energy
|
Defined as the abilit to do work.
|
|
Kinetic energy
|
Energy associated with motion.
|
|
Potential energy
|
Is the stored energy that a body has because of its position. ex. when you lift an object up
|
|
Work
|
Defined as the product of the force applied to a object and the distance through which the force is applied.
