Acceleration
What is a change in velocity
100
What will happen when object A, applies a force to object B?
What is object B will begin to move.
100
Finish the phrase: "An object in motion stays in motion and...
What is "an object at rest stays at rest unless acted on by an unbalanced force"?
100
The formula for Newton's 2nd Law
What is force equals mass times acceleration?
100
Newton's 3rd Law states that...
What is "every action has an equal and opposite reaction"?
200
Thrust
What is a reaction force that pushes an object forward.
200
What happens when an object at rest or in motion experiences an unbalanced force?
What is it will change direction or begin to travel.
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
Draw an example of Newton's 3rd Law.
What is when two objects are applied with the same amount of force and are traveling at each other the will bounce back in the opposite direction.
300
Pendulum
What is A weight hung from a point so it can swing freely backward and forward.
300
What causes an object to accelerate?
What is a force.
300
Draw an example of Newton's first law. (Use whiteboards)
What is when a car is stopped by a tree a loose object will continue in motion.
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"?
400
Velocity
What is the rate of change of position along a straight line with respect to time.
400
How does the laws of motion help us to better understand motion?
What is it allows us to explain motion or it helps us know how objects move.
400
Another name for Newton's First Law.
What is the law of inertia?
400

Theory
What is a set of statements or principles devised to explain a group of facts.
500
What other terms tie in with motion? (2)
What is friction and gravity.
500
Why does a penny not follow the card instead of dropping in the cup in the second lab experiment?
What is because the penny has a tendency to resist the motion of the the card.
500
Which would have a greater acceleration, a small car or a large car, if the same force is applied?
What is the small car.
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.
