100

the formula for Newton's 2nd Law

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.

200

gravity

What is "the force that pulls two objects toward one another, generally downward"?

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.

Which of Newton's Laws take force into consideration?

What is "all of them"?

300

the distance from one object to another is changing

What is "motion"?

300

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"?

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

Mrs. Wallace is going down the sidewalk on her skateboard; Mrs. Hierholzer decides to get on too. What will Mrs. Wallace have to do to keep the skateboard moving at the same velocity?

What is "push with more force"?

400

a change in a moving object's speed or direction

What is "acceleration"?

400

Another name for Newton's First Law.

What is "law of inertia"?

400

What is "*any acceptable answer*"

400

Mrs. Clark is driving down the road in her car and she has a glass of water. She has to stop very quickly. What happens (specifically!) to the water in the glass and why?

What is "the water spills on the radio because it has inertia and wants to continue moving forward even though the car has stopped"?

500

inertia

What is "an object's tendency to resist any change in its motion"?

500

Why did the penny not move with the hoop in the example from lab last week?

What is "because the penny had inertia"?

500

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

What is "a small car"?

500

What is "counter-clockwise"?

500
