An objects tendency to resist movement is called ________.
Inertia

What is Newton's 1st Law
Newton's First Law is that an object at rest will stay at rest and an object in motion will stay in motion until an unequal force acts upon it.
100
What two things affect the strength of gravity?
The mass of the objects and the distance between them.

If you kicked a soccer ball while in outer space it would travel at the same speed in the same direction potentially forever. Which of Newton's Laws is this an example of?
Newton's 1st Law
100
Two teams are playing tug-o-war, they are pulling the rope but it isn't moving one way or another. This shows that the forces are _________.
balanced
200
A force that pulls things towards the center of the Earth is called ___________.
Gravity
200
What is Newton's Second Law?
The acceleration of an object depends on the mass of an object and the size of the force acting on it.
200
When you drop a ball and it lands on the ground, this is caused by __________.
Gravity
200
A ball at rest on the ground. It will stay at rest until a force acts on it. This is an example of which of Newton's Laws
First Law of Motion
200
If an object like a chair is at rest, what two forces are action on it?
Gravity pulls the chair down, the floor pushes the chair up
300
Any push or a pull is called __________.
Force
300
What is Newton's Third Law?
Newton's Third Law is that for every action there is an equal and opposite reaction.
300
When you kick ball into the air it eventually comes back down, the two forces acting on it are ___________.
gravity and friction
300
The amount of force needed to throw a bowling ball is much greater than the force required to throw a baseball. This is an example of which of Newton's Laws?
Newton's 2nd Law
300
What is the invisible force that causes materials such as iron to stick to other metals? What causes it?
Magnetism. The movement of electrons.
400
A change in an objects speed or direction is called _______.
Acceleration
400
When we measure force, what unit do we use?
Newtons
400
The force of Gravity is greater between two objects that have __________.
that have greater mass.
400
When you paddle a kayak through the water, the paddle pushes against the water which causes the kayak to travel in the opposite direction. This is an example of which of Newton's Laws of motion?
Newton's 3rd Law
400
TRUE or FALSE: When two bumper cars of the same mass are traveling towards each other and they collide, they will bounce back an equal distance
True
500
A change in an objects speed or direction is called _______.
Motion
500
What are three of Newton's other contributions to science?
Telescopes Calculus Gravity Light Astronomy
500
Who first noticed gravity and gave it its name?
Sir Issac Newton
500
How does Newton's Second Law of Motion explain why it is easier to push a toy car than a real car?
The Second Law of Motion explains that to move objects with more mass more force is required, so the toy car would take much less force to move than the real car.
500
The first law of motion says that the reason we wear a seat belt is because if the car stops suddenly our bodies will continue to move at the same speed in the same direction because of _____________.
Inertia
