Newton Facts
In what year was Sir Isaac Newton born?
1642
Sir Isaac Newton's only discovery was the 3 Laws of Motion.
False. Newton is also known for inventing the reflecting telescope and discovered calculus.
2nd Law
You are cross country skiing, using ski poles to push yourself forward. Pushing yourself with the ski poles is the...
Action.
These two forces don't exist in space, so if you threw a ball, it would keep going for a very long time.
Gravity and friction
When did Sir Isaac Newton die?
1727
Newton's 2nd Law might require you to do some math calculations.
True.
This Law states that every action has an equal and opposite reaction.
3rd Law
A lobster flips its tail quickly to swim backwards. Identify the action and reaction.
Action- lobster flipping its tail.
Reaction- the lobster swims backwards.
You kick a soccer ball down the field. No one touches it, but it eventually stops rolling. Which force is responsible?
Friction
Where did Sir Isaac Newton live?
England
Gravity is a force.
True.
This Law states that an object in motion will stay in motion and an object at rest will remain at rest unless acted upon by an outside force.
1st Law
A rocket pushes hot gases down which causes the rocket to launch upward. What is the action and reaction?
Action: hot gases push down
Reaction: rocket moves up
A semitruck takes longer to accelerate from a stop than Mr. Watts' truck. Why?
Because the semitruck has more mass than Mr. Watts' truck.
Where did Newton study?
Cambridge University
It requires the same amount of force to throw a bowling ball the same distance as a tennis ball.
False.
"A book sitting on the table does not move"
This scenario is an example of which Law?
1st Law
A basketball player pushes forward to run down the court. What is the action?
pushing forward
You have 2 blocks of equal size. One is made of styrofoam and the other is made of steel. Which has more mass?
The block of steel will have more mass.
What event happened that led to Newton discovering the concept of gravity? (and eventually the 3 Laws of Motion)
Newton saw an apple fall from a tree and wondered why it fell to the ground.
The larger the object, the more gravity it will have.
True. Jupiter is much larger than Earth and has more gravity. If you weigh 100 pounds on Earth you would weigh about 250 pounds on Jupiter!
A skateboarder pushes the ground backward which causes the board to move forward.
3rd Law
A baseball player swings a bat and hits a homerun. Name the action and reaction.
Action: swinging the bat
Reaction: homerun
What is the difference between mass and weight? (hint: remember the moon scenario we talked about).
