Am I stuck? (Newton's 1st Law)
Fill in the blank:
Objects at rest stay at rest, until acted on by an external _______
Force
Two objects are accelerating at the same speed. One is 5 kg, the other is 10 kg. Which object needs more force to go just as fast?
10 kg
I hit a bowling ball with my hand with 10N of force. How much force does the bowling ball hit my hand with? (Include the unit!!!)
10 N
F = ma
An object with 10kg is accelerating at 2 m/s2. What is the force? (Need unit!!!)
20N
What was Newton's Book called?
Principia
In the real-world, a bowling ball will eventually stop moving, even if no person is around to stop it. Why?
Friction
Pushed with the same force, what accelerates faster: a 4 kg box, or a 400 kg box?
4 kg box.
Fill in the blank: Every action has an equal and _______ reaction
Opposite
What word is this definition: the tendency to resist a change in motion.
Inertia
What is the unit for Force? (Write out the full word - spelling doesn't count as long as it's close enough!)
Newton
In a game of mini golf, do you need more or less force to overcome gravity and hit the golf ball up a hill?
More
What is the mathematical formula for Newton's 2nd Law?
F = ma
When a book sits on a table, the table exerts a force on the book in the opposite direction of _______ (one word)
Gravity
m = v*s
An object is moving at 15 m/s, and travels for 10 seconds. What is the distance traveled? (Need Units!!!)
150m
Isaac Newton's family owned a _____ that he was not interested in working in.
Orchard or Farm
Do unbalanced or balanced forces make an object change motion?
Unbalanced
Two objects with the same mass are accelerating at different speeds. One fast, one slow. Which object experienced a higher force?
Fast
Two rollerbladers are going forward, and then they accidentally collide. Immediately afterwards, they start rolling backwards. This is an example of Newton's _____ Law.
3rd or Third
a = F/m
How much does a 2 kg box accelerate if a force of 10N is applied to it? (Need units!!!)
5 m/s2
Bigger objects generally have more of this, and need more Force to accelerate because of it.
Mass

Inertia
Which of these objects needs the most force to move:
A normal-sized car,
A normal-sized school bus,
A jumbo jet.
Jumbo Jet
What is the force that opposes almost all movement on the ground?
Friction
(No formula given. Use the boards!)
An object is moving at 10 m/s for 10 meters. For how long has the object traveled?
1 second
Isaac Newton used a lot of this much older Scientist's work. They are often compared together.
Galileo
