Friction
Force that opposes the motion between two surfaces that touch.
What is friction?
Force of attraction that pulls objects towards the center of the Earth.
What is gravity?
Objects with different masses falling towards Earth, have the same velocity or the same acceleration?
What is acceleration?
This has more air resistance. A crumpled sheet of paper or a flat sheet of paper.
What is a flat sheet of paper?
First man on the Moon.
Who was Neil Armstrong?
This type of friction occurs when force is applied to an object and the object moves.
What is kinetic friction?
This determines the gravitational force between two objects.
What is mass?
The quantity pf the acceleration due to gravity on Earth is this.
What is 9.8 m/s2 ?
Force that keeps an object moving in a circular path.
What is centripetal force?
The amount of bones sharks have.
What is Zero?
This type of friction occurs when force is applied to an object and the object does not move.
What is static friction?
The measure of the gravitational force on an object is known as this.
What is weight?
An object at rest is dropped from the top of a building and hits the ground after a time of 4 seconds. Find the stone's velocity when it hits the ground.
What is 39.2 m/s ?

When you apply a lubricant between two surfaces, it does this to friction.
What is reduce it?
This remains constant no matter which planet in the universe you are on.
What is mass?
Force that opposes the motion of falling objects is known as this.
What is air resistance?
An object is doing this when it is going around another object in space.
What is orbit?
The traditional wrapping for sushi.
What is seaweed?
Putting sand on icy roads, is necessary to do this to friction so the vehicles don't slide.
What is increase it?
All objects in the universe attract each other because of gravitational force is known as this.
What is the universal law of gravitation?
Is the speed of an object when the force of air resistance equals the force of gravity.
What is terminal velocity?
Is the motion of an object when gravity is the only force acting on the object.
What is free fall?
He killed Han Solo.
Who is Kylo Ren?
