An object at rest stays at rest, and an object in motion stays in motion at a constant speed and in a straight line unless acted on by an unbalanced force
What is Newton's First Law of Motion
100
The acceleration of an object depends on the mass of the object and the amount of force applied
What is Newton's Second Law of Motion?
100
Whenever one object exerts a force on a second object, the second object exerts an equal on opposite force on the first
What is Newton"s Third Law of Motion?
100
Newton's summarized ideas about gravity
What is the law of universal gravitation?
200
The force that opposes the motion of objects through the air
What is Air Resistance?
200
Examples are a chair on the floor and a golf ball on a tee
What are examples of an object at rest?
200
The amount of matter in an object
What is mass?
200
Example is applying a force to a chair when you sit on it
What is an example of forces acting in pairs
200
A British scientist who realized that the questions, why do objects fall toward Earth, and what keeps the planets moving in the sky, were 2 parts of the same question
Who is Isaac Newton?
300
The constant velocity of a falling object when the force of air resistance is equal in magnitude and opposite in direction to the force of gravity
What is Terminal Velocity?
300
a force that causes a change in motion
What is an unbalanced force?
300
It is always in the same direction as the acceleration of an object
What is similar in direction to the net force applied on an object
300
Example is the force applied by the chair that pushes up on your body
What is an example of a reaction force?
300
Italian scientist who questioned Aristotle's idea about falling objects
Who is Galileo Galilei?
400
The motion of a body when only the force of gravity is acting on the body
What is Free Fall?
400
The unbalanced force that causes a desk to stop moving when it is sliding across the floor
What is friction?
400
Example of this is pushing on an empty cart then pushing on a full cart with the same and different force
What is an example of Newton's second Law?
400
Example is a bat exerting a force on the ball and sends the ball flying. The ball exerts an equal force on the bat.
What is an example of action and reaction force pairs
400
It depends on size, shape and the speed of an object
What does the magnitude of air resistance depend on?
500
A place in which there is no matter
What is a Vacuum?
500
Another name for Newton's First Law of Motion
What is the Law of Inertia?
500
The cause of an an object to move
What is a push or pull?
500
A force of attraction between objects that is due to their masses
What is gravity?
500
The curved path that an object follows when thrown, launched , or otherwise projected near the surface of the Earth
