1.dynamic -- a impulse
2.surrounds every object -- b newton 2nd law
3.impulse= momentum -- c.newton 1st law
4. f . t -- d.study of cause of motion
5. resist change in motion -- e gravitational field
true or false
1.motion in a circle at a constant speed is not considered accelerated motion
2. the changing velocity vector for uniform circular motion points toward the center of the circle.
3. centripetal means center-seeking
4. a planet located sixteen times the earth distance from the sun would travel at one forth of the earths speed around the sun
5. a boy swings a rock around himself by pulling on a string. suddenly the boy releases the string. the rock will go tangential to the circle.
6.when a car rolls to a stop momentum is still conserved
7. both action and reaction forces are applied to the same object
8.the acceleration due to gravity is 32m/sec^2
9.if the mass of each cart is equal, the velocities of the cart will be equal after the spring is released.
10.the further a planet is from the sun the faster the planet moves
11.the moons circling jupiter support the geocentric theory
12.keplers second law states that a line from the sun to a planet sweeps out equal areas in equal times.
13.keplers third law shows the square of the radius of a planet orbit divided by the cube of the planet period is a constant
