This is a force that pulls objects towards each other.
What is gravity?
100
This is an object that orbits another object.
What is a satellite?
100
An object at rest remains at rest, the object in motion stays in motion until an unbalanced force acts upon it.
What is Newton's First Law?
100
A push or pull.
What is a force?
200
This relates to air resistance.
What is fluid friction?
200
This states that the force of gravity acts between all objects in the universe.
What is Universal Gravitation?
200
This explains how satellites continuously fall but travel around Earth.
What is satellite motion?
200
Resistance to a change in motion.
What is inertia?
200
An SI unit that measures the strength of force.
What is a Newton?
300
A skateboard has wheels that roll in a direction while this friction acts in the opposite way.
What is rolling friction?
300
Go to the moon and this is different than when it was on Earth.
What is weight?
300
Makes things go in a circular path.
What is a centripetal force?
300
Acceleration = Net force / Mass
What is Newton's Second Law?
300
Gravity is the only force acting on an object.
What is free fall?
400
This acts in the opposite direction to the intended motion.
What is static friction?
400
This is how big something is.
What is mass?
400
Why some satellites go around the Earth in 2 or 24 hours.
What is satellite location?
400
Mass x Velocity.
What is momentum?
400
Greatest velocity.
What is terminal velocity?
500
Two surfaces exert on each other.
What is friction?
500
A leaf and an acorn fall, this makes the leaf fall slower.
What is air resistance?
500
How the rocket can rise.
What is Newton's Third Law?
500
If an object exerts a force on another object, then the object must exert a force of equal magnitude and opposite direction back on the original object.
