any push or pull

### 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.

P=mv

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
