Name that Law
Misc.
100
Another name for Newton's 1st law.
What is Inertia?
100
The formula for Newton's 2nd law of motion.
What is F=ma?
100
To every action there is an equal and opposite reaction. This is another word for action.
What is force?
100
Why do dishes stay on a table when a tablecloth is pulled off of the table?
The inertia of the plate resists change of motion. Not enough force to change motion.
100
Mass is the same thing as weight. (true or false)
What is false.
200
An object will stay at rest (or in motion) until...
What is acted on by an unbalanced force
200
When an object changes velocity or direction.
What is accelerate?
200
The reaction force (or force pair) to a hammer putting force on a nail.
What is a nail putting force to the hammer?
200
A volleyball player hits a volleyball with her forearms and it bounces off.
What is Newton's 3rd Law of Motion?
200
The resistance of an object to any change in motion is called...
What is inertia?
300
This causes an object to change velocity or direction.
What is an unbalanced force?
300
All of the matter in an object.
What is mass?
300
The gravitational force that Earth exerts on the moon compared to the gravitational force the moon exerts on Earth.
What is equal or the same?
300
Two children on a sled go faster than one child on a sled.
What is Newton's 2nd Law of Motion?
300
A car is driving at a constant speed of 50 mph while another car is driving at a constant speed of 90 mph. Which car is accelerating faster?
What is neither car is accelerating?
400
An object that has inertia will move at this rate.
What is a constant speed.
400
A semi-truck and a Mini Cooper are racing. Which one will get to 60 mph first? Why?
The Mini Cooper will accelerate faster because it has less mass.
400
Mr. Davis runs into a wall. The force that Mr. Davis puts on the wall is equal to the force that the wall puts on Mr. Davis. This is why Mr. Davis bounces off the wall and the wall doesn't move.
What is Mr. Davis has a smaller mass?
400
Why does a satellite keep going around Earth at a constant speed without stopping?
What is Newton's 1st Law of Motion? (or inertia)
400
This is why a person on Earth doesn't fly away when we push a button or turn a doorknob.
What are gravity and friction?
500
Why does the semi-truck take longer to stop than the Mini Cooper?
The semi-truck has more mass, so it has more inertia. So, it resists a change in motion more. It will take a greater force to stop it.
500
At the end of a race between a semi-truck and a Mini Cooper, which one will take more force to stop? Why?
The semi-truck because it has more mass so it will take more force to accelerate it to a stop.
500
Give an example of Newton's 3rd law of motion.
Any example that shows one object exerting a force on another object in an equal and opposite direction.
500
Why the astronaut was repelled by the spaceship when he pushed on it.
What is Newton's 3rd law of Motion?
500
If I change the mass of an object, then the force of that object will change because F=ma. What is the independent variable?
Changing the mass.
