###
mass

is the amount of matter in an object.

###
weight

is the measure of gravitational pull on an object

###
inertia

an object at rest stays at rest, an object in motion stays in motion. more mass=more inertia

###
How does the slop of the ramp affect the distance a car travels when it is released?

The greater the slope of the ramp the greather the car's velocity.

###
speed

is the distance an object travels in a certain amount of time S=D/T

###
momentum

is the measure of an amount of force moving objects have p=mv

###
What is Newton's third law?

Every ation there is an equal and opposite reaction

###
Why is it crucial to know the volocity of a tornado?

Velocity tells us the speed and direction.

###
acceleration

Is the rate at which the velocity of an object changes

###
What is a newton?

It is the unit of measurement for force. It is the force required to accelerate a 1Kg mass at s rate os 1 m/s2.

###
To find acceleration?

A=(Vf-Vi)/t

###
Potential energy

(mass)(acceleration due to gravity)(height)

###
Kinetis energy

K.E.=1/2(mass)(velocity)2

###
Give two examples of kinetis and potential energy?

K.E.-thermel energy (heat) and sound.

P.E.-gravitational potente energy and glastic potential energy.

###
Calculate how much force is required?

F=mass*acceleration

F=60Kg*10m/s2

F-600 N
