Give three statements on Newtons 2nd law about
Direction of Motion
How acceleration affects the force
How the Force changes with mass
Object Moves in the direction of the net Force
Foces Increases as accelration increases
as mass increases Force Decreases

An object in motion stays in motion, an object at rest stays at rest until acted on by an outside force.
Newton's 1st Law

What Law is Action / Reaction?
Newton's 3rd Law

A baseball bat hits a ball. Besides flying through the air, what does the ball do?
Hits the bat with equal and opposite force
200
When an object is not in motion it has an ________________ forces.
Balanced

This law explains why a balloon flies around the room when you let it go without tying it.
Newton's 3rd Law
200
The term used for the resistance of an object to changes in its state of motion, as described in Newton’s First Law.
Inertia
200
When an object is in motion it has _______________ forces.
Unbalanced?

According to Newton’s Second Law, increasing the force applied to a mass has this result.
Increases acceleration of the object

A box is being pushed to the right across the floor. What force is acting on it on the floor?
Friction
300
The unit of force is this.
Newton
300
In Newton's Second Law, if mass is constant and force increases, this must also increase.
Acceleration
300
Mass has this unit.
kg, kilogram

What is the Net Force?
What is 50?

If you want to increase the acceleration of a baseball when you throw it, what must you increase to make this happen?
Force
500
A net force of zero results in this type of motion, according to Newton’s First Law.
Constant velocity or no motion
500
If a heavier object needs more force to move than a lighter one, you’re seeing this law in action.
Newton’s Second Law (F = ma)
500
What is velocity?
How fast something(an object) is moving in a given direction.
