Circular Motion Review

Centripetal Motion

100

Name one important day-to-day application that utilizes centripetal motion

Driving a car, turning a faucet, turning a doorknob, etc. 

200

This describes how a velocity is applied within centripetal motion (aka how is located on the circle)

Tangent to the circle

300

This is the direction that the Centripetal Force is always pointed. 

Towards the center of the circle

400

Which of the original Newton's Laws applies to Centripetal Motion to calculate the force applied. 

Newton's 2nd Law

500

When turning in a circle with your car, what is the type of force that keeps you moving centripetally (hint: not centripetal force). 

Force of friction

Universal Gravitation

100

This is the name of the big G in the universal gravitation equation

Gravitational constant

200

Name an application or industry that benefits from the use of universal gravitation

Astronomy, space exploration (NASA), Meteorology, Satellite applications (internet, phones, etc.), Microbiology, Chemistry, Modern Physics 

300

True or False: A more massive object pulls in smaller objects through universal gravitation

True

400

What does the r within the formula stand for, and how is it found

Radius, and it is measured as the distance between the center of one mass to the center of another. 

500

How can we use both Centripetal and Gravitational Forces together to solve complex problems (hint: think of your lab)

We can solve for Centripetal force of a system if we know the masses of the objects involved (as well as the distances and the initial velocity), which can allow us to see how different planetary bodies pull on one another within a solar system. It can even lead to outstanding discoveries such as black holes when these items don't add up. 

Extra Physics Knowledge

100

Our most recent unit

Waves

200

The first unit covered in this class

Kinematics

300

Unit that was covered when making roller coasters and what this lab demonstrated about this unit

Energy, and it demonstrated that it transforms from potential energy to kinetic energy throughout its travel (aka conservation of energy)

400

This unit was one of our largest and covered what happens when we move objects in space and accelerate them. What is this unit and name 3 of the types of this unit we covered

Forces. Gravitational Force, Normal Force, Push Force, Frictional Force, Centripetal Force, Spring Force.

500

This unit covered what happens when two objects collide into one another and either stick or don't stick. Name that unit, and what each of these types of interactions is called

Momentum, and inelastic vs. elastic collisions
