200

Another word for "force of gravity"

Weight

200

200

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

What is "a net force acts on a mass"?

200

When a baseball bat comes into contact with a baseball, which object experiences more force?

Neither, the forces are equal

200

Which of Newton's Laws take force into consideration?

What is "all of them"?

300
a push or pull
What is "force"?
300

What is the word for "resistance to change in motion"?

Inertia

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

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. Use Newton's 3rd law to explain this phenomenon 

What is "the action is pushing off of the side of the pool, the reaction is being propelled forward"?

300

Angelina is going down the sidewalk on her skateboard; Erin decides to get on too. What will Angelina 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

Which of the following has the greatest inertia? Person, car, motorcycle, train

Train

400

As the force on an object increases while the mass stays constant, acceleration will.....

increase

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. One of the dummies doesn't have a seat belt on. What happens to the crash test dummy without the seatbelt? State which of Newton's Laws this follows

What is "the dummy flies out the window because an object in motion wants to stay in motion." (Newton's First Law)
