2. Newton’s 3 laws of motion discovered by the one and only...

3. Newton’s First Law
An object in motion continues in motion with the same speed and in the same direction unless acted upon by an outside force.
"the law of inertia".
Inertia: The tendency for a body to remain unchanged in its motion. The more mass it has the more inertia it has.

4. Newton’s Second Law
F=ma

5. Calculate the weight of the basketball.
A basketball has a mass of .623kg. A basketball player throws a ball straight up in the air, the ball leaves his hand with an acceleration of around What is the force the player exerts on the ball?
Calculate the weight of the basketball.
Calculate the Normal Force on the basketball.

6. How much force is required to keep a 5-kg object moving rightward with a constant velocity of 2 m/s if there is no friction?

7. Newton’s Third Law
For every action there is an equal and opposite re- action. (Forces are equal in all exchanges.)

8. Which exerts more force on the other object?
Forces are equal but the accelerations are not!

9. Which exerts more force on the other object?
Which car changes acceleration the most?
