Basic Physics Motion Terms

Is equal to the force times the distance and is measured in joules

The magnitude of _____ is the object's speed. The rate of change in an object's position

The measurement of how fast an object moves relative to a reference point

Standard unit of measure for energy and work

Is equal to the change in velocity over change in time. Is a vector

Standard unit of measure for pressure

A quantity that has both a magnitude and a direction

Is equal to the mass times the velocity of an object

Measurement of how much matter is in an object. Usually measured in kilograms

Standard unit of measure for force

On Earth, pulls with an acceleration of 9.8 m/s^2. Force caused when the mass of bodies attract

States that greater the mass of an object, the more force it will take to accelerate the object

States that for every action there is an equal and opposite reaction

Vector measured in newton-seconds. A measurement of mass in motion.

Measured in pascals. The force over a given area

Occurs when any two objects bump into each other

The measurement of the change in an object's velocity.

Scalar quantity measured by distance over time.

Scalar quantity calculated using formula KE = 1/2 * m * v^2, where m = mass and v = velocity

Measured in newtons. Force of gravity on an object

Vector measured in newtons. The measurement of a push or pull on an object

A basic mechanical device for applying force and doing work. EX: Pulley, screw, and wedge

Standard unit is the joule. The ability to do work

Is calculated by dividing work over time

Is a force and measured in newtons. The resistance of motion when one object rubs another

States that any object in motion will continue to move unless external forces act on it

A change in momentum

A measurement that only measures the magnitude. Does not have a direction

Refers to an object's overall change in position. It is a vector quantity

The Standard unit of power

Measured in Joules. The energy stored by an object due to its state or position

The energy an object has due to its motion

Standard unit is the watt. Measurement of the rate at which energy is used

A force acts on an object to move it some distance
