Newton's Laws Cont'd
100
When a train increases its velocity, its momentum....
What is increases?
100
An object in motion stays in motion and an object at rest stays at rest until an unbalanced force acts on it.
What is Newton's First Law of Motion?
100
This is why astronauts appear weightless in space.
What is free fall?
100
This is the constant velocity of a falling object when the force of gravity is balanced by the force of air resistance.
What is terminal velocity?
100
All forces act in pairs.
What is Newton's Third Law of Motion?
200
A quantity defined as the product of the mass and velocity of an object.
What is momentum?
200
The tendency of an objects to resist any change in motion.
What is inertia?
200
The gravitational rate.
What is 9.8 m/s/s
200
The curved path that an object follows when thrown, launched, or otherwise projected near the surface of Earth.
What is projectile motion?
200
The acceleration of an object depends on its mass and the amount of force applied.
What is Newton's Second Law of Motion?
300
The mass of the combined objects is equal to the masses of the two objects added together, in this kind of collision.
What is sticking together?
300
F = m x a
What is Newton's 2nd Law equation?
300
The combination of forward motion and free fall.
What is orbital motion?
300
Force of attraction between objects that is due to their masses.
What is gravity?
300
A common unbalanced force that opposes motion.
What is friction?
400
The equation for momentum.
What is p = m x v?
400
A measure of inertia.
What is mass?
400
The rate at which a ball travels once it has left the pitcher's hand (hint: not a number).
What is constant?
400
A combination of all forces acting on an object.
What is a net force?
400
The law that works together with the Conservation of Momentum.
What is Newton's 3rd Law?
500
The example in the book that was used to show the conservation of momentum during an 'objects bouncing off each other' collision.
What are a bowling ball and bowling pins?
500
Whenever one object exerts a force on a second object, the second object exerts an equal and opposite force on the first.
What is Newton's 3rd Law?
500
When an object is traveling around another object.
What is orbiting?
500
The rate at which velocity changes over time.
What is acceleration?
500
The type of force that causes objects at rest to move and to change the acceleration of a moving object.
What is an unbalanced force?
