What does Newton mean?
|
Newton stands for meter/second/second or meters/second2
1N=1kg. x 1 m/s/s. |
|
Three Types of Friction
|
1. Slding
2. Rolling 3. Fluid |
|
Friction depends on Two things.
|
1. The surface of the objects
2. The material of the objects |
|
What is air resistence
|
Air resistence makes a falling object slow down.
|
|
Force
|
A force is a push or a pull
|
|
How can prevent friction?
|
Use lubercants such as oil and wax.
|
|
Balanced Forces
|
Balanced forced will relsult in no motion because they are equal and oppisite.
|
|
Mass
|
The amount of matter in an object.
|
|
Unbalanced Forces
|
Unbalanced forces result in motion. The object will get accelerated.
|
|
Universal Gravitation
|
Every object with a mass has a gravitational pull and it depends on two things.
1. The mass of the object 2. The distance between the objects |
|
Terminal Velocity
|
When the upward force of air equals the downward force of gravity and acceleration stops therefore reaching constant velocity.
|
|
Vector
|
Line with an arrow.
|
|
Prijectile Motion
|
If you shoot something horizontally and vertically out the same time they will land at the same rate.
|
|
Second Law of Motion
|
Acceleration ,mass or inertia, and force are all related.
Force=Mass x acceleration |
|
First Law of Motion
|
An object will remain at constant speed or at constant rest forever unless outside forces ineract.
|
|
Inertia
|
The property of matter that to resist any change in motion.
|
|
Third Law of Motion
|
For every action there is an equal and oppisite reaction. Forces come in pairs.
|
|
Friction
|
The force that causes objects to slow down and eventually stop.
|
|
Weight
|
The measure of the force of gravity on an object.
