What does Newton’s 1st law say about an object at rest?
An object at rest stays at rest UNLESS acted on by an unbalanced force.
100
What does the amount of acceleration depend on?
The amounts of force and mass.
100
What always comes in pairs?
forces
100
Draw and Label an example of Newton's 1st Law.
Your drawing must show an object at rest being made to move by an unbalanced force, or an object in motion being made to change its motion by an unbalanced force.
100
Where did Sir Isaac Newton live?
In England
200
What does Newton’s 1st law say about an object in motion?
An object in motion stays in motion at the same velocity UNLESS acted on by an unbalanced force
200
If the amount of force applied doubles, then the acceleration will: double
If the amount of force applied doubles, then the acceleration will also double
200
Action and reaction pairs are always what and what?
Equal in size and opposite in direction
200
Draw and label an example of Newton’s 2nd law
Your drawing must show how objects with more mass have less acceleration, or how applying more force increases acceleration. You could show overcoming inertia.
200
Why did Newton leave college and go home?
The plague was in London.
300
What is another name for Newton’s 1st law?
"The Law of Inertia"
300
Action and reaction forces do not cancel each other out because:
they act on different objects
300
Draw and label an example of Newton's 3rd law.
Your drawing must show an action/reaction pair of forces, where there is an opposite, equal force in opposite directions (such as a baseball hitting a glove, and the glove applying an equal amount of force back on the ball)
300
Did Newton make most of his discoveries as a young man or an old man?
Newton was in his 20's when he made most of his discoveries (he was college age)
400
What is inertia?
The resistance of an object to a change in motion.
400
Acceleration DECREASES with mass BECAUSE:
the amount of inertia INCREASES and/or you need more force
400
In a collision, the object with MORE mass has MORE:
inertia

Newton came up with the law of gravity while sitting under an apple tree. Draw this event, and label it with all the forces.
Drawing should show gravity pulling on Newton, and support force of the ground under him. Show the gravity pulling the apple down.
400
Besides working on the Laws of Motion, what else did Newton investigate?
Light, color, astronomy
500
Without THIS force, an object in motion would keep moving forever.
Friction
500
What is the mathematical equation for Newton’s 2nd Law?
F = M x A OR A = F/M
500
In a collision, the object with MORE mass will have LESS:
Acceleration (change in velocity)

Imagine you are on one of the gym scooters. You push off with your feet and roll across the floor until you hit the wall. Where are Newton's 1st, 2nd and 3rd' laws in effect?
Newton's 1st: The scooter is at rest until you push. The scooter moves until it is stopped by the wall. Newton's 2nd: The harder you push (the more force) the faster you will go. If you weigh less, you will require less force to go fast. Newton's 3rd: When you hit the wall, the wall pushes back on you.

How long ago did Sir Isaac Newton live?
In the 1600's
