What is Newton's 1st Law of Motion?
Force = Mass x Acceleration
An object at rest stays at rest unless acted on by an unbalanced, external force
What goes up must come down
For every action, there is an equal and opposite reaction.
What is Newton's 2nd Law of Motion?
Force = Mass x Acceleration
An object at rest stays at rest unless acted on by an unbalanced, external force
What goes up must come down
For every action, there is an equal and opposite reaction.
What is Newton's 3rd Law of Motion?
Force = Mass x Acceleration
An object at rest stays at rest unless acted on by an unbalanced, external force
What goes up must come down
For every action, there is an equal and opposite reaction.
True or False: objects with greater mass require more force to accelerate when compared to objects with less mass.
True
False

Marshmellow
Quarter
Marble

What does the first part of Newton’s first law say about objects in motion?
Objects in motion speed will increase.
Objects in motion speed will decrease.
Objects will move at the same speed and direction unless force changes their motion.
Force does not affect the change in an objects motion.
Isaac Newton stated for every action there is an
_________ and _________ reaction.
equal and same
equal and opposite
unequal and same
unequal and opposite

While you’re ice-skating with your friends, you push off from one end of the rink and slide forward. Based on Newton’s first law of motion, what is true?
You will lose your balance and fall over before your reach the middle of the ice rink.
You will continue to slide across the ice until a force makes you stop or change direction.
The force of gravity will make you keep your velocity until your friends make you stop.
The size of your ice skates will determine how quickly or slowly you travel across the ice.
Your friend kicks a soccer ball, and it stops a few feet from you. What needs to happen to it in order for it to return to your friend?
Friction has to be applied to the ball.
Force has to be applied to the ball.
Speed has to be applied to the ball.
Inertia has to be applied to the ball.
What does friction do to a moving object?
Makes it rise
Slows it down
Speeds it up
All of the above
How is velocity different from speed?
Velocity is when an object goes in reverse.
Velocity is the direction an object moves in, and it has nothing to do with speed.
Velocity is speed and direction together.
Velocity is not at all different from speed.
You are riding in the car with your grandfather, and he turns left. Why do you shift to the right?
It takes you a moment to catch up with the new velocity of the car.
You have more inertia than the car, so it take longer for you to turn left.
You had been sitting at rest until the force of the turn set you in motion.
The car continued in the same velocity, but you had a different inertia.
The rate at which an object’s velocity changes is called what?
inertia
actualization
acceleration
completion
Every time your cat’s paw hits her toy string, it swings away from her. How does this demonstrate Newton’s third law of motion?
Objects with mass, such as your cat's paw and toy string, will require inertia.
Objects in action, such as the string toy, will experience force.
For every motion from your cat's paw, there is unbalanced inertia from the string.
For every action your cat makes, there is an equal and opposite reaction from the string.
A softball and a volleyball collide with equal speed, and then they accelerate at the same rate. What must be true about the masses of the objects?
The softball has more mass than the volleyball.
The softball and the volleyball have equal mass.
The volleyball has more mass than the softball.
It is impossible to compare the mass of the softball and the volleyball
