Momentum
100
This Italian scientist proved that heavy and light objects actually fall at the same rate.
Who is Galileo Galilei?
100
This the measure of the pull of gravity on an object.
What is weight?
100
This is a push or pull.
What is Force?
100
In Newton's 2nd law, acceleration equals THIS.
What is force/mass or Force = m x a?
100
This is the product of the mass and velocity of an object.
What is Momentum?
200
Because of THIS, all objects accelerate, or speed up, toward Earth at a rate of 9.8 m/s/s.
What is Gravity?
200
An object does this when going around another object in space.
What is orbit?
200
This is the total force acting on an object.
What is Net Force?
200
This Newton's Law suggest that all forces act in THESE. (2 parts)
What is Newton's 3rd Law and pairs?
200
This is how momentum is calculated.
What is p(momentum) = m (mass) x v (velocity)?
300
This is the force that opposes the motion of falling objects.
What is Air resistance?
300
This is the force that keeps an object toward the center of a circle.
What is Centripetal Force?
300
This Newton's Law describes objects that have no unbalanced forces, or no net force, acting on them. It has these two parts. (3 parts)
What is Newton's first law, an object at rest will remain at rest and an object moving at a constant velocity will continue to move at a constant velocity?
300
When a person is sitting on a chair, THIS is the person's weight pushing down on the chair. Additionally, this is the chair pushing back up on the person. Together they are know as this. (3 Parts)
What is action force, reaction force, and force pair?
300
This law states that when a moving object hits an object at rest, some or all of the momentum of the first object is transferred to the second object.
What is The Law of conservation of momentum?
400
This is the speed of an object when the force of air resistance equals the force of gravity.
What is Terminal Velocity?
400
This must be applied to an object to change its direction.
What is an unbalanced force?
400
This is the ability of an object to resist any change in motion.
What is Inertia?
400
True or False: A truck and car traveling with the same velocity have the same momentum.
What is false?
400
This is how the momentum of a car can be increased. (2 parts)
What is increase its velocity and/or mass?
500
This is the motion of an object when gravity is the only force acting on the object.
What is Free Fall?
500
This is the curved path an object follows when it is thrown near the Earth's surface. List the two motions it combines. (3 responses)
What is Projectile Motion and Horizontal and Vertical Motion?
500
This Newton's Law describes how an object moves when an unbalanced force acts on it. It's comprised of these two parts. (3 Parts)
What is Newton's 2nd Law and acceleration of an object depends on its mass and force applied?
500
This is a quantity whose value does NOT change.
What is constant?
500
True or False: During a collision, the total momentum of the two objects changes.
What is false?
