Inertia- The tendency of an object in motion to stay in motion, and an object that is stopped to remain stationary. An object that has a greater mass has greater inertia which explains why object in free fall have the same velocity.

Vector- Something with size/magnitude and direction-ex. velocity Scalar- Something with nothing but size/magnitude doesn't contain direction-ex. speed Circular Motion- The motion of an object in a circle that is accelerating. This is also called Centripetal Force. Fc=mv2/r Energy- A conserved substance-like quality with the ability to cause change; it is measured in joules and is not created or destroyed Friction- A non-conservative force, caused by rubbing against a foreign surface. a. Static friction- frictional force existing before the object moves. b. Kinetic friction- frictional force that exists while the object is moving. Momentum- the quantity of motion, measured as a product of its mass and velocity. Impulse- the change in the momentum of a body, as a result of force acting upon it. Elastic- "bounce off". If you have an elastic collision the objects bounce off each other. m1v1+m2v2=m1v1+m2v2 Inelastic- "sticks together". If you have an inelastic collision the objects stick together and move with a different velocity, and a mass of the objects combined. m1v1+v1v2=(m1+m2)v2 Net Force- is the total amount of forces combined. Newtons- is the unit we measure force in. Joules- the unit we measure energy in. Grams- the unit we measure mass in. Work- is anything acting on a system that is considered to be an outside force. W=(delta)E

Delta-the change in; Δ (Ex: Δx= change in position)

Potential energy- due to position or configuration. (Eg)

Elastic energy- deformation(Eel)

Kinetic energy- due to motion (Ek)

Internal or dissipated energy- (Ediss)(Eint) is mostly due to friction which causes heat.

Projectile- anything where the only force on an object is Fg.

Coefficient of Kinetic Friction- (Uk) you multiple the Uk times the force and you will get the friction force, only if this object is moving. Ffk=UkFn

Coefficient of Static Friction- (Us) you multiple the Us times the force and you will get how much friction force is being applied to keep the object stationary. Ffs=UsFn

Intercept- the loading force it takes to move.

Conservative force- path independent. This means this force can always be there, another force doesn't have to happen for this one to too. (Ex: Fg)

Non-Conservative- Path-dependent. This relies on another force. (Ex: Ff)

2-D Motion- When an object is moving vertically and horizontally

Tangent- A single point on a graph, usually an x vs t graph. It usually indicates instantaneous veocity

Independent Variable- The variable that is changed and controlled by the researcher throughout the experiment. Goes on the x-axis

Dependent Variable- The variable that changes based on the independent variable. Goes on the y-axis
