What is inertia
100
What is the that velocity changes over a period of time
What is acceleration
100
What is air resistance
What is the force that opposes the motion of objects through air
100
Examples of projectile motion
What is a frog leaping, water sprayed by a sprinkler, a swimmer diving into water
100
Other force of gravity between Earth and a falling object is....
What is force pair
200
_______ is the measure of inertia
What is mass
200
The curved path that an object follows when thrown, launched, or otherwise projected near the surface of the Earth?
What is projectile motion
200
Newton's third law of motion states
What is whenever one object exerts a force on a second object the second object exerts an equal an opposite force on the first object
200
How can calculate the change in velocity of a falling object
What is (triangle)v=g x t
200
Galileo questioned ARISTOTLE's idea about free fall what did he argue
What is the mass if an object does not affect the time the object takes to fall to the ground
300
Why do objects fall towards earth
What is objects accelerate towards Earth because the force of gravity pulls them toward Earth
300
Newton's second law is represented by the following equation.....
What is F=m x a
300
Where does pull things on earth to
What is the center
300
The unbalanced force that causes objects to move in a circular path is called
What is centripetal force
300
Why do objects appear weightless while in orbit
What is they are in free fall
400
What gives an object in projectile vertical motion
What is gravity gives vertical Morton to an object in projectile motion
400
When you ride a bus, why do you fall forward when the bus stops moving
What is when the bus is moving, both you and the bus area in motion. When the bus stops moving, no unbalanced force acts on your body so your body continues to move forward
400
What is the relationship between the force on an object and the objects acceleration
What is the acceleration of an object increases as a force exerted on the object increases
400
What is Newton's first law of motion
What is an object at rest remains at rest and an object in motion remains in motion at constant speed and in a straight line unless acted by an unbalanced force
400
How are the forces in each force pair related?
What is the forces in a force pair are equal in size and opposed in directions
500
Suppose a baseball and a marble are dropped at the same time from the same height
. Which ball would land according to Aristotle? Explain
What is the baseball because he thought that the rate at which the object falls depends on an objects mass
500
What is the acceleration due to gravity.
What is 9.8meters/second/second
500
Will air resistance have more effect on the acceleration of a falling leaf or acorn.
What is leaf
500
What does the word centripetal mean?
What is toward the center
500
The motion of a body when only the force of gravity is acting on the body
