Newtons Laws
Gravity and Motion
Momentum
100
When only gravity is pulling down on an object and no other forces are acting on it.
What is Free Fall?
100
An object at rest remains at rest, an object in motion remains in motion at a constant speed and in a straight line unless acted on by an unbalanced force.
What is Newton's First Law?
100
All objects accelerate toward earth at a rate of 9.8 m/s/s.
What is the velocity of falling objects?
100
P=M x V
What is momentum's formula?
200
When an object stops accelerating and is at a constant velocity.
What is Terminal Velocity?
200
The acceleration of an object depends on the mass of the object and the amount of force applied.
What is Newton's Second Law?
200
Air Resistance depends on an object's size, shape, and speed.
What is Air Resistance?
200
When a moving a moving object hit another object, some or all of all the momentum of the first object is transferred to the object that is hit. If only some of the momentum is transferred, the rest of the momentum stays with the first object.
What is The law of Conservation of Momentum?
300
A curved path an object follows when it is thrown or propelled near the surface of the 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 on the first.
What is Newton's Third Law?
300
An object is orbiting when it is travelling around another object in space.
What is Orbiting?
300
The mass of the combined objects is equal to the masses of the two objects added together. In a head-on collision, the combined objects move in the direction of the object that had the greater momentum before the collision.
What are objects that stick together?
400
The tendency of all objects to resist any change in motion.
What is Inertia?
400
The law that depends on the mass and force applied to see acceleration.
What is Newton's Second Law?
400
An unbalanced force that causes objects to move in a circular path.
What is Centripetal Force?
400
During these types of collisions, momentum is usually transferred from one object to another object. The transfer of momentum causes the objects to move in different directions at different speeds.
What are objects bouncing off each other?
500
Depends on the object's mass and velocity.
What is Momentum?
500
Newton's Third Law.
What is the law that has action and reaction forces?
500
Motion that is perpendicular to the ground. Pulls thrown objects down.
What is Verticle Motion?
500
A force was the action force, the reaction force was equal but opposite force exerted by the action force. Momentum is neither gained nor lost.
