The motion of a body when only the force of gravity is acting on the body.
What is Free Fall?
100
An object at rest remains at rest, and an object in motion remains in motion.
What is Newton's First Law of Motion?
100
Change in V= g x t.
What is Velocity of Falling Objects?
100
Objects fall to the ground at the same rate because the acceleration due to gravity is the same for all objects.
What is Gravity and Acceleration?
100
The ______ of an object depends on the object's mass and velocity.
What is Momentum, Mass, and Velocity?
200
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?
200
The acceleration of an object depends on the mass of the object.
What is Newton's Second Law of Motion?
200
F= m x a.
What is Newton's Second Law Formula?
200
The acceleration of an object is the object's change in velocity divided by the amount of time during which the change occurs.
What is Acceleration Due to Gravity?
200
When a moving object hits another object, some or all of the momentum of the first object is transferred to the object that is hit.
What is The Law of Conservation of Momentum?
300
The curved path that an object follows when thrown, launched, or otherwise projected near the surface of Earth.
What is Projectile Motion?
300
Whenever one object exerts a force on a second object, the second object exerts an equal and opposite force.
What is Newton's Third Law of Motion?
300
A ball is dropped from a bridge it hit the ground in 2 seconds what's the velocity of the ball?
Change in V= g x t
Change in V= 9.8m/s x 2 sec=
What is 19.6 m/s down?
300
The amount of _______ acting on an object depends on the size, shape, and speed of the object.
What is Air Resistance and Falling Objects?
300
The mass of the combined objects is equal to the masses of the two objects added together.
What is Objects Sticking Together?
400
The tendency of an object to resist being moved or, if the object is moving, to resist a change in speed or direction until an outside force acts on the object.
What is Inertia?
400
All forces act in pairs.
What is Newton's Third Law of Motion?
400
An apple falls from a tree and hits the ground in 4 seconds, what was the velocity of the apple?
Change in V= g x t
Change in V= 9.8m/s x 4sec=
What is 39.2 m/s down?
400
Weight is a measure of gravitational force. The size of the force depends on the masses of objects and the distances between them.
What is Orbiting Objects Are in Free Fall?
400
P= m x v
What is the calculation of Momentum?
500
A quantity defined as the product of the mass and velocity of an object.
What is Momentum?
500
An object that has less mass has less inertia, while an object that has a larger mass has more inertia.
What is Mass and Inertia?
500
P=m x v
What is the Formula for Momentum?
500
An object is orbiting when it is traveling around another object. When a spacecraft orbits Earth, it is moving forward, but it is also in free fall.
What is Two Objects Combine to Cause Orbiting?
500
During these types of collisions, momentum is usually transferred from one object to another.
