What is Force?
A push or pull on an object.

Explain why a magician can pull a tablecloth from under plates, and have the plates stay on the table?
The plates are at rest, so they want to stay at rest.

What is Newton's 2nd Law
F=ma or The acceleration of an object is dependent on two variables, the force acting upon the object and the mass of the object.

If I apply the same force to a ping pong ball and a bowling ball, which one will accelerate shorter and slower?
bowling ball

Opposite forces that are equal are called ....
Balanced forces

What is Newton's 1st law?
An object at rest will stay at rest unless acted upon by an outside force and an object in motion will stay in motion unless acted upon by an outside force.

What is a balanced force?
The forces Equally acting upon an object to cause it to stay motionless or the forces equally acting upon it to cause constant motion.
500
What is an unbalanced force?
When forces are unequally applied to an object, in opposite directions. Generally the objects are moving to help you know there is an un balance of forces.
500
What causes an object to move?
Force causes the object to accelerate. Which cause the object to be in a state of unbalanced forces.

When 2 vehicles heading towards each other at the same velocity, but one has more mass than the other vehicle? What happens?
The vehicle with more mass will come out of the accident with less damage, because it had more mass.

Sally challenges you to a race. On the first turn you run off the course and your car strikes a large bale of hay. Your car still produces 500 N of force, but now it accelerates at only 2 m/s2. What is the mass of your car now that the bale of hay is stuck to it?
250kg
