An object will accelerate only if.....
The net force does not equal zero
An object will remain at constant velocity or will remain at rest when...
The net force on the object equals zero.
Another word for "force of gravity"
Weight
Finish Newton's 2nd Law: Acceleration occurs when...
What is "a net force acts on a mass"?
When a baseball bat comes into contact with a baseball, which object experiences more force?
Neither, the forces are equal
Which of Newton's Laws take force into consideration?
What is "all of them"?
What is the word for "resistance to change in motion"?
Inertia
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"?
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"?
Which of the following has the greatest inertia? Person, car, motorcycle, train
Train
As the force on an object increases while the mass stays constant, acceleration will.....
increase
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)
The amount of matter contained within an object.
Mass

15th, 16th, 17th, 18th
16th
Why does a sled sliding across the snow eventually stop if Newton's 1st Law says an object in motion stays in motion?
What is "friction"/unbalanced force?
