What is Newton’s First Law?
An object in motion stays in motion with constant velocity, and an object at rest stays at rest if there is no unbalanced force exerted on it.
The acceleration of an object is directly proportional to the net force on the inversely proportional to its mass.
When a force is exerted on an object, the object will exert an equal and opposite reaction.
Eating apples that fell off the tree is good.
An object is at rest with zero net force, what is the velocity of the item after 1 hour?
0 m/s
5 m/s
10 m/s
20 m/s
What is Newton’s 2nd Law?
An object in motion stays in motion with constant velocity, and an object at rest stays at rest if there is no unbalanced force exerted on it.
The acceleration of an object is directly proportional to the net force on the inversely proportional to its mass.
When a force is exerted on an object, the object will exert an equal and opposite reaction.

What is Newton’s 3rd Law?
An object in motion stays in motion with constant velocity, and an object at rest stays at rest if there is no unbalanced force exerted on it.
The acceleration of an object is directly proportional to the net force on the inversely proportional to its mass.
When a force is exerted on an object, the object will exert an equal and opposite reaction.

Which of the following best demonstrates the principle of Newton’s Third Law?
For every exerted force, there is an equal force to it.
For every exerted force on an object, there is an equal & helping force to it.
For every exerted force on an object, there is an equal & opposite force to it.
For every exerted force on an object, there is an unequal & helping force to it.
Newton’s Third Law explains that there should be a net force acting on an object for it to accelerate.
True
False
Newton’s Third Law demonstrates the concept that every force acting on an object has an equal and opposing force to it.
True
