100
A push or pull on an object.
What is a Force?
100
The equation for calculating the amount of friction?
What is Ff = u Fn
100
The force is directly related to the masses of two objects. If one mass doubles, this force doubles.
What is gravity?
100
This force would be 1/4 as strong if the moon were moved to twice its distance from Earth.
What is the force of gravity?
100
The SI unit of force.
What is Newton (N)?
200
A force that opposes motion.
What is friction?
200
The equation for calculating a spring constant.
What is Hooke's Law? F = k x
200
This type of force prevents an object from even starting to move. It tries to keep the object in one spot.
What is Static Friction?
200
The SI unit for length?
What is meter (m)?
300
The interaction between two forces that cause an object to travel in a curved path.
What is projectile motion?
300
A 35 N piece of wood is slid across the surface of a piece of glass. Calculate the force of friction if the coefficient of friction is 0.07.
What is 2.45 N?
300
A feather falls to Earth slower than other objects because of this force?
What is Fluid Friction?
300
This person developed a model of gravity that states that objects with mass stretches and warps space like a fabric.
Who is Albert Einstein?
300
This is the SI unit of acceleration?
What is m/s^2?
400
A property of materials to return to its original shape after being stretched or compressed.
What is elasticity?
400
How big is the elastic force when a spring (k = 0.75 N/m) is compressed by 0.25 m?
What is 0.2 N?
400
Robert Hooke determined how to calculate this force in 1660.
What is Elastic Force?
400
On Earth all objects accelerate towards the center of the Earth at a rate of 9.8 m/s^2 due to this force.
What is the force of gravity?
400
The SI unit for a spring constant.
What is N/m?
500
A circular motion around a massive object caused by gravity
What is an orbit?
500
If a 10 N object stretches a rubber band by 0.6 m, what is the spring constant of the rubber band?
What is 16.7 N/m?
500
The amount of surface area, mass, and the type of texture an object has are all things that affect this force?
What is friction?
500
This law states that the gravitational force is the same everywhere in the universe.
What is Law of Universal Gravitation?
500
This is the SI unit for weight.
