What is Newton's First Law?
What is Newton's First Law?
An object in motion stays in motion unless a force acts on it. An object at rest stays at rest unless a force acts on it.
What is Newton's Second Law?
What is Newton's Second Law?
The force acting on an object can cause the object to speed up, slow down, or change direction.
What is Newton's Third Law?
What is Newton's Third Law?
When one object exerts force on a second object, the second object exerts force on the first. These forces are equal in strength and opposite in direction.
The greater the net force acting on an object, the ________ the acceleration of the object.
The greater the net force acting on an object, the ________ the acceleration of the object.
greater
What happens when an object accelerates?

If you were building a car to enter a downhill race, what can you do to make your car go as fast as possible?
If you were building a car to enter a downhill race, what can you do to make your car go as fast as possible?
Make the car heavier to move faster down hill and give it smooth shape to reduce air resistance.
