Mass
What is mass?
A measure of the amount of matter in an object.
What is friction?
The force that two surfaces exert on each other when they rub against one another.
What is momentum?
A quantity defined as the product of the mass and velocity of an object.
What is terminal velocity in free fall?
The constant velocity of falling objects when the force of air resistance is equal in magnitude.
What is the SI unit for mass?
m=mass
What are the types of friction?
Static, kinetic, rolling, fluid, and sliding.
What is the SI unit for momentum?
p=momentum
What is projectile motion?
The curved path that an object follows when thrown, launched, or projected near the surface of the earth.
What is the equation to find mass?
m=p/v
When does sliding friction occur?
When two solid surfaces slide over each other.
When will momentum increase?
It will increase if the mass or velocity increases.
What is a verticle concept?
It would run straight down if there was no air resistance.
What is the difference between mass and weight?
Mass never changes, weight does depending on the pull of the gravity.
What is an object in static friction?
Between objects that are not moving or have no motion.
How is force related to momentum?
When an object is forced to change its motion, the momentum is changed.
True or false? Would gravity pull on a vertical concept?
True.
What causes mass?
The strong force that is pulling at it, and you.
When does fluid friction occur?
When a solid object moves through a fluid.
What does time have to do with momentum?
The more time changes, the momentum occurs at a smaller force.
What relationship does the moon have with projectile motion?
Projectile motion is the reason the moon orbits the Earth and the planets orbit the sun.
