1
Which is the best description of Newtons Second Law?
Force is only affected by acceleration
Force is equal to mass times acceleration
Things with small mass hit with lots of force if they move slow
Force is only affected by mass
2
Which of Newton's laws explains why the blue car goes from being still to moving?
All three laws
Newtons 3rd
Newtons 1st
Newtons 2nd
3
Why is Pikachu bouncing off of Snorlax?
Pikachu uses his lightning powers to jump
The force from his fall bounces him back with INCREASED force
The force of his fall bounces him in the OPPOSITE direction
Snorlax's snores blow him back up
4
Which of Newton's laws explains why the blue car accelerates quickly enough to go around the loop?
Newtons 1st
All three laws
Newtons 2nd
Newtons 3rd
5
In physics, what is the definition of MASS?
How large something is
Weight
The amount of matter something is made of
Both size and weight combined
6
Which of Newton's laws is this an example of?
Newton's Second law - force is equal to mass times acceleration
Newtons' First Law - unbalanced forces are needed for something to move
Newtons' 3rd - for every action there is an equal and opposite reaction
All three laws
7
Which of Newton's laws explains why the blue car bounces off of the button?
Newtons 2nd
All three laws
Newtons 3rd
Newtons 1st
8
In physics, what is the definition of ACCELERATION?
A change in speed
A change in speed OR direction
How fast something is going
When something speeds up
9
Which of Newton's laws is this an example of?
Newton's Second law - force is equal to mass times acceleration
All three laws
Newtons' First Law - unbalanced forces are needed for something to move
Newtons' 3rd - for every action there is an equal and opposite reaction
10
What is a good description for Newton's First Law
Force, mass and acceleration are all connected
All things with the same mass move with the same amount of force
Balanced and unbalanced forces are the same thing
Things only move when affected by an unbalanced force
11
Why is this bowling ball hitting with so much force?
Red, Blue and Yellow are all correct
It is being pushed with a large unbalanced force
It is being accelerated to a fast speed
It has got a lot of mass
12
What is an "UNBALANCED FORCE?"
When objects bounce off each other
The same force going in all directions
More force going one way than another
What needs to happen for something to stay still
13
Which is the best description of Newton's 3rd law
For every action there is an equal and opposite reaction
Acceleration is equal to mass divided by force
Pikachu is the bounciest pokemon
Reactions are always weaker than actions
14
Why is the cat moving forwards?
The dog is creating an unbalanced force
The dog is creating a balanced force
It's an optical illusion!
The cat is pulling with more newtons than the dog
