physics final

a body that is falling downward, only in a vacuum; all bodies fall with the same acceleration

newton's second law (3)

a diagram showing all of the forced acting on  an object 

speed at which the acceleration of a falling object is zero because friction balances the weight

the terminal speed together with the direction of motion

a mutual action

newton's third law (4)

the mass of the object multiplied by its velocity

a vector quantity that is equal to the product of the net external force that acts on the system and the time interval during which the force acts, the impulse is in the same direction as the net external force and it equals the resulting change in momentum 

the identified object or collection of objects that will interact

the ability of an object to produce a change in itself or the world around it

the product of the net force an object and the distance through which the object moves as a result of net force

the rate at which energy is transformed or the rate at which work is done

the ability to do work

energy related to the forces and position or configuration between an object and its surroundings

energy stored in a system including an object and the earth due to the gravitational force between the earth and the object and the elevation or height of the object above or below a reference level

the form of energy an object has becaue of its motion

energy cannot be created nor destroyed
