Basic Physics Motion Terms

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

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

The energy an object has due to its motion

The Standard unit of power

Standard unit of measure for pressure

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

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

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

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

A force acts on an object to move it some distance

A change in momentum

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

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

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

A quantity that has both a magnitude and a direction.

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

Scalar quantity measured by distance over time.

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

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

Is equal to the mass times the velocity of an object

Standard unit of measure for energy and work

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

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

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

Standard unit of measure for force

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

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

Occurs when any two objects bump into each other

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

Measured in newtons. Force of gravity on an object

Standard unit is the joule. The ability to do work

Is calculated by dividing work over time

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

Measured in pascals. The force over a given area.
