Momentum
100
A push or a pull.
What is a force?
100
A force that opposes motion between two surfaces that are in contact.
What is Friction?
100
A force of attraction between objects that is due to their masses.
What is Gravity?
100
An object at rest will remain at rest unless acted upon by and outside force and an object in motion will remain in motion unless acted upon by and outside force.
What is Newton's First Law of Motion?
100
P=m*v
What is the equation for Momentum? What is the equation for Momentum?
200
The measurment of force.
What are newtons?
200
Friction between moving surfaces.
What is kinetic friction?
200
What is gravity?
The gravitational force that pulls all objects toward each other.
200
A golfball sitting on a peg and is at rest and when a person swings the club and hit the golfball of the peg the golfball is now in motion because the club hit the golfball and created an unbalanced force.
What is an example of Newton's First Law of Motion?
200
The product of mass and velocity of an object.
What is The defination of Momentum?
300
The combination of all forces.
What is net force?
300
When a force is applied to an object but doesn't make the object move.
What is static friction?
300
Garavity equals 9.8m/s/s
What is the rate at which every object falls to the ground?
300
The acceleration of an object depends on the mass of the object and the amount of force applied to the object.
What is Newton's Second Law of Motion?
300
Complete this statement: The momentum before a collision is equal to
What is the momentum after the collision?
400
An object that has 0 newtons.
What is a balanced force?
400
When an object is being rolled by a force.
What is rolling friction?
400
Describes the relationship between gravitational force, mass, and distance.
What is the law of universal gravitation.
400
When a person is pushing a cart and the cart is empty they dont need to excert a lot of force on and the acceleration of the object is high because the object has a small mass and when the cart is full the person needs to excert more of a force and the acceleration is smaller because the mass is bigger than the empty cart.
What is an example of Newton's Second Law of Motion?
400
Some or all the Momentum is transferred from one object to another the second object will go moving in the direction of the unbalanced force and if only some of the momentum is tranfreed the first objects keeps its momentum.
What is the Law of Conservation of Momentum?
500
when objects have newtons higher than 0.
What is an unbalanced force?
500
A liquid that can reduce friction.
What are lubricants?
500
A measure of the gravitational force exerted on an object; it's value can change with the location of the object in the universe.
What is weight fromthe book?
500
Whenever one objects excerts a force on a second object, the second object excert excerts an equal and opposite force on the firsrt.
What is Newton's Third Law of Motion.
500
Fill in the blank: _____ is the path taken when an object is thrown.
What is Inertia?
