200
gravity
What is "the force that pulls two objects toward one another, generally downward"?
200

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

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

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
