In uniform circular motion, acceleration is

towards the center of an object

In UCF, net force is

towards the center of an object

In elliptical circular motion, dose Velocity and force increase or decrease when closer to orbiting an object?

increase closer to orbiting object

In ECM, velocity is

outward and tangent

The orbit of the planet if affected by the…

mass of the star, speed of the planet and the distance from the star to the planet

kepler’s 1st law

The sun is at one side of an orbital ellipse because planets orbit in an elipse

Kepler’s 2nd law

Planets don’t move with constant speed in their orbits (closer = faster), and the areas are almost of equal size

Kepler’s 3rd law

The time a planet orbits the sun decreases with a decrease in radius and increases with an increase in radius (t² = r³)

If the radius is doubled the velocity is…

doubled

If the temperature of a gas is held constant while the volume is decreased by half, what will the new pressure be?

Doubled

If the volume of a gas is held constant while the temperature is halved, what will the new pressure be?

Halfed

Relationship of volume and pressure

v = 1/p

Relationship of volume and temperature

V = T

Relationship between pressure and time

P = T

Pressure equation

p = k/v

Relationshipbetween volume and temp

v = t

The relationship between acceleration and radius

a = 1/r

Finding the relationship of variables using equations

Variables on the same side have the inverse happen to them but it’s the opposit side then the same thing happens
