The Nature of Force
Newton's Laws
Friction and Gravity
100
Any object that orbits another object in space.
What is a satellite?
100
In free fall, this force is an unbalanced force, which causes an object to accelerate.
What is gravity?
100
This is described by its strength and by the direction in which it acts.
What is force?
100
An object at rest will stay at rest and an object in motion will stay in motion.
What is Newton's first law?
100
The force that two surfaces exert on each other when they rub against each other.
What is friction?
200
Any force that causes an object to move in a circular path.
What is centripetal force?
200
This increases with air resistance.
What is velocity?
200
This type of force acts on an objects results in a net force and a change in the object's motion.
What is an unbalanced force?
200
Force equals mass times acceleration.
What is Newton's second law?
200
The friction that acts on objects that are not moving.
What is static friction
300
Pushes the rocket's exhaust gases downward.
What is action force?
300
The greatest velocity a falling object reaches.
What is terminal velocity?
300
This type of forces actions on an object does not change its motion.
What is a balanced force?
300
Every action has an equal opposite reaction.
What is Newton's third law?
300
Friction that acts on objects that are not moving.
What is static friction?
400
Gases send the rocket to space.
What is reaction force?
400
An object that is thrown.
What is a projectile?
400
Any object that causes an object to move in a circular path.
What is centripetal force?
400
F=ma
What is the formula for Newton's second law?
400
This law states that the force of gravity acts between all objects in the universe.
What is universal gravitation?
500
Two factors that affect the gravitational attraction between objects.
What is mass and distance?
500
In the absence of air, two objects with this difference fall at the exact same rate.
What is mass?
500
This object can be put into low orbit of less than 1,000 kilometers.
What is a satellite?
500
Inertia
What is Newton's first law?
500
Objects falling through air experience a type of fluid friction.
What is air resistance?
