First Law
This is another name for Newton's 1st Law of Motion
Law of Inertia
What is the equation used for Newton's 2nd Law?
F = M x A
This force causes an object to move
Action force
This law explains why heavier objects require more force to accelerate.
2nd Law
Which scientist created the three laws of motion?
Isaac Newton
Inertia is determined by this
Mass

4800 N
Action and reaction forces that work together are called what?
Force pairs
This law explains why a passenger standing on a bus falls backward when the bus suddenly speeds up
1st Law
Newton developed his ideas about gravity after observing this object fall from a tree.
Apple
Two equal forces acting in opposite directions is what type of force
Balanced forces
What is produced when a force acts on a mass?
Acceleration
What is Newton's 3rd Law?
For every action, there is an equal and opposite reaction
This is why a book on a table will stay still unless someone pushes it
1st Law
How many scientific books did Isaac Newton write?
2
What is Newton's 1st Law?
An object at rest will remain at rest, or an object in motion will remain in motion, unless acted on by an unbalanced force.
A bowling ball and a tennis ball are kicked with the same force. Which ball will accelerate more?
Tennis
When you walk, your feet push a force down on the ground. What is the reaction force?
The ground pushes a force up on your feet
A frog leaping upward off his lily pad is pulled down by gravity and lands on another lily pad instead of continuing in a straight line.
3rd Law
What job did Newton's mother want him to pursue?
Farmer
These two forces cause an object act as unbalanced forces to stop objects from moving
Friction and Gravity
What is the unit used for force? What is the unit used for acceleration? What is the unit used for mass?
Force = N
Acceleration = m/s2
Mass = kg
You push a shopping cart forward with 30 N. According to the 3rd Law, how much force and what direction does the cart push on you?
30 N backward
A swimmer pushes water back with her arms, but her body moves forward.
3rd Law
This is the country Isaac Newton was born in.
