How does the gravitational field vary with the mass of the object creating it?

The strength of the gravitational field between two objects is inversely proportional to the square of the distance between them.

Newton's Law of Universal Gravitation states

Anything that has mass has a gravitational field of attraction

Considering the conservation of angular momentum (L), what happens when a spinning ice skater extends their arms away from their body?

  1. They slow down.

  2. Their angular velocity (ω) decreases.

What’s the difference between kinetic energy and potential energy?

Kinetic energy is the energy due to motion while potential energy is the energy due to position

200

Elastic collisions conserve which quantities?

momentum and energy

In what type of medium do waves travel the quickest through?

Solid

Yellow: What circuit component limits the flow of current in a circuit and is designed to dissipate energy in the form of heat?

Resistor

What are 3 factors that affect speed of sound?

Temperature, medium, + density

How does the electric potential energy of a charged particle change as it moves in an electric field?

The electric potential energy of a charged particle changes as it moves in an electric field because the electric field does work on the particle.

A glass rod is rubbed with a silk cloth. Glass is above silk in the triboelectric series. What happens to the electrons in the glass?

The glass gives away electrons

If the momentum of an object is tripled, how much force is needed to achieve this change in momentum?

The force required would also need to be tripled.

When analyzing projectile motion, this is the only quantity that would necessarily be the same value in both the horizontal-x and vertical-y columns of the data.

What is it called when an object's natural frequency of vibration matches the frequency of an external force, which results in an increase of amplitude? 

Resonance

What’s the difference between work and power?

Work is the energy transferred to or from an object by a force acting on it over a distance, while power is the rate at which work is done.

In what type of mathematic relationship would the current of the entire circuit change when a capacitor is charging (assume a circuit with just a battery and a capacitor)?

Exponentially

yellow A 12V battery is connected in series with a 10 ohm resistor and a 5 ohm resistor. What is the total resistance in the circuit, and what is the current flowing through the circuit (with units)?

0.8 Amps

What are 3 factors that affect speed of sound?

Temperature, medium, + density

What is the relationship between the period and frequency of simple harmonic motion?

The period of simple harmonic motion is the time it takes for one complete cycle of the motion, while the frequency is the number of cycles per unit time

If the Earth is at this point in orbit, this can determine the length of a total solar eclipse. The Earth reaches this point approximately soon after the June solstice. Name this point where a body is the most distant from the sun.

Why is it safer to jump from a greater height into water than onto a hard surface?

The longer the time over which a force is applied (i.e. the greater the impulse), the smaller the force required to achieve a given change in momentum.
