Newton's First Law
Newton's Second Law
Newton's Third Law
Which Law?
100

causes an object to change its motion

What is "an unbalanced force"?

100

State Newtons First Law

What is "An object in motion stays in motion and an object at rest stays at rest unless acted on by an unbalanced force"?

100
the formula for Newton's 2nd Law
What is "F=ma"?
100
Newton's 3rd Law states that...
What is "every action has an equal and opposite reaction"?
100
A tennis ball is served, the tennis player on the other side of the net swings at the ball but misses. This law explains why the ball stays in motion until it hits the fence.
What is "Newton's 1st Law"?
200

an attractive force between any two objects with mass

What is "gravity?"

200
In the following example, what is the unbalanced force: A car is driving down the street, but comes to an abrupt stop when it hits a tree.
What is "the tree"?
200

Finish Newton's 2nd Law: Acceleration occurs when...

What is "a force acts on a mass"?

200

Give an example of Newton's 3rd Law.

Ex: Your foot pushes backward on the ground, but you move forward.

200

Which law explains why it hurts when you run into a wall?

What is "Newtons Third Law"?

300

a push or pull

What is "force"?

300

Give an example of Newton's first law.

Ex: When you run with a bucket of water and suddenly stop, the water splashes out of the bucket because it will continue to do what it was already doing.

300
If a force of 10N occurs on a mass of 2kg, what must be the acceleration? (remember to use appropriate units!)
What is "5 m/s/s"?
300
***DAILY DOUBLE*** A swimmer pushes off the side of the pool and is propelled forward by the force of the pool exerting a force on the swimmers foot. Explain this in terms of Newton's 3rd Law.
What is "the action is pushing off of the side of the pool, the reaction is being propelled forward"?
300

Ms. DiLo is going down the sidewalk on her skateboard; Ms. Epps decides to get on too. Which of Newton's Laws explains why Ms. DiLo will have to push with more force to keep the skateboard moving at the same velocity?

What is "Newtons 2nd Law"?

400

a change in an object's speed or direction

What is "acceleration"?

400
Another name for Newton's First Law.
What is "law of inertia"?
400

Give an example of Newton's 2nd Law.

Ex: When you push an empty grocery cart and a full grocery cart with the same force, the empty grocery cart will change speed faster because it has less mass.
400
Explain the action and reaction forces acting on a book resting on a table.
What is "action force is the weight of book on table - reaction force is a force equal to the books weight pushing up from the table onto the book."
400

Safety researchers are simulating a head-on collision using crash test dummies to represent what happens to people in these situations. One of the dummies doesn't have a seat belt on. Which law explains why the crash test dummy without the seatbelt hits the concrete barrier?

What is "Newtons First Law?"

500

the tendency of an object to keep doing what it was already doing

What is "inertia"?

500

Which of the following has the greatest inertia? A) Person B)Car C)Jet D)Train Why?

What is "train"? It has the greatest mass

500

Which would have a greater acceleration, a small car or a large car, if the same force is applied? Why?

What is "a small car"? Because a small car has less mass.

500
While repairing the Hubble Telescope, which is in space, an astronaut turns a screwdriver clockwise. What direction will the astronaut turn?
What is "counter-clockwise"?
500

Which law explains why a marble on the floor slows down and eventually stops rolling?
