It is a push or pull acting upon an object as a result of its interaction with another object

What is the unit for newton

Force usually act in pairs

Forces usually can be seen and their effects on an object

What is the formula for Force

Is the formula for Acceleration = F/m

Known as the resultant force, a single force that acts and causes a change in state of motion of an object

No changes in the state of motion are produced

Applied force makes an effort to move across it, opposes the motion of object.

A force that transmits through string rope or wire when it is pulled tight

This force is exerted when a spring returns to its normal shape

A force that pulls objects toward each other because they have mass

What is the gravity measurement (include m/s^2) 

An object at rest remains at rest or an object in motion remains in motion of constant speed unless acted upon by a net force

Inertia is directly proportional to the magnitude of the net force and inversely proportional to its mass

The greater the gravitational pull, the greater its inertia

GRESA

Whenever one object exerts a force on a second object the second object exerts an equal magnitude but opossite direction of force on the first object

An object of mass has 15kg accelerated upward at 2m/s^2

What is the mass of an object if a force of 20N causes it to accelerate at 1.5m/s^2

Dust coming out of mat when beaten

For every action there is an equal and opposite reaction

Standing in a subway train and the train suddenly stops but your body continues to move forward

2 cars hit head on

An apple is falling down from the tree

Force = Mass x Acceleration

Astronauts in space

The ability to do work

The unit for energy is joules (J)

ALL matter is made up of particles, the particles NEVER stop moving

What are the 2 major types of mechanical energy

Stored energy and is associated with the position of the object

The types of potential energy: Chemical, Elastic and Gravitational

Energy associated with the relative position of an object in space near earths surface

Y is the horizontal position of mass

1 joule = 2kg x m2/sec2 = 1Nm

What is the formula for PE

Associated with the motion of an object

What is the formula of Kinetic energy

The velocity of an object is doubled when the KE is quadrupled

Acceleration is m/s^2, while the velocity is..

The potential energy is at its greatest when the movement is at its greatest

Law of Conversion; Energy cannot be ______________, only change from one form to another

Energy is constantly transforming but never dissapears

In getting the KE what is the first step

And what is the second step in getting KE

It is a disturbance that travels through a medium

Frequency = waves/time

The speed of sound, like all waves depend on the...

Sound travels fast in liquid and slowest in gas

The lower the temperature the slower sound travels

At 0° C, the speed of sound in air is __________ m/s

What is the speed of sound at 35° C

What is the speed of -120° C

What is colors

What color is refracted the least because it has the longest wavelength

What color is refracted the most because it has the shortest wavelength

Produces very bright beams of light

Related to the average kinetic energy of particles in a substance
