100
Push or pull of an object
What is a force?
100
The amount of matter in an object.
What is mass?
100
The greatest velocity that an object reaches.
What is terminal velocity?
100
The product of its mass and its velocity.
What is momentum?
100
Any object that travels around another object in space.
What is satellite?
200
The sum of all the forces acting on an object.
What is net force?
200
The force required to accelerate one kilogram of mass at one meter per second per second.
What is a Newton?
200
Three types of friction
What is sliding friction, rolling friction, fluid friction?
200
That the total momentum of the objects that interact does not change.
What is Law of Conservation of Momentum?
200
Any force that causes an object to move in a circle.
What is centripetal force?
300
Can cause an object to start moving, stop moving, or change direction.
What is unbalanced forces?
300
The net force on an object is a product of acceleration and its mass.
What is Newton's Second Law of Motion?
300
When only force acting on a falling object is gravity.
What is free fall?
300
For every action there is an equal and/or opposite this.
What is reaction?
300
Satellites orbit around earth continually fall toward earth, but don't because of this.
What is because earth is curved?
400
Equal forces acting on one object in opposite directions.
What is balanced forces?
400
An object at rest will remain at rest and an object in motion will remain in motion until a unbalanced force acts upon it.
What is Newton's First Law?
400
An object that is thrown.
What is projectile?
400
The total momentum of any group of objects remains the same unless outside forces do this.
What is act on the objects?
400
This burns fuel and produces gases and pushes gases downward then at the same time applies an equal force to this pushing it upwards.
What is a rocket?
500
The tendency of an object to resist change in its motion.
What is inertia?
500
If you have two forces pushing acting on an object with the same amount of force, the net force is this.
What is zero?
500
Objects falling through air experiencing a type of fluid friction.
What is air resistance?
500
The SI unit for momentum.
What is kg X meters/second
500
Even though a satellite is pulled downward by gravity, it stays in orbit because of this.
What is the satellite is moving so quickly?
