Chapter 2 Honors Physical science ODDS

REMEMBER read every question carfully. On the test one word can change your entire answer.

Discontinued the idea that continued motion was required to keep something moving.

Which of Aristotles Ideas did galileo discredit with his inclined plane experiments

Equal to the height of its orgional position.

You make a pendalum If you raise the ball a given distance how high will it swing on the other side

The piece of iron has more mass but less volume. The pillow has less mass but more volume. The reason is because their density differs.

which has more mass a 2kg pillow or a 3kg iron weight? Which has more volume?

The upward force is the tension on the vine. The downward force is due to gravity. Both are equal when the monkey is stationary.

A monkey hangs stationary at the end of a vine. What are the forces acting on her. Which force if either is greater.

The player is not at rest or not moving at a constant velocity, so the player is not at equilibrium.

can a basketball player halfway through a jump in midair be at equilibrium? Why or why not?

A person on a diet loses mass, To lose only weight the person could go to the top of a mountain where gravity is less. But the amount of matter would be the same.

Does a person on a diet more accurately lose mass or lose weight? Defend your answer.

A; ball on track B finishes first because it has a greater average speed than A

B: Yes ball B rolls faster on the lower track
C: Yes, the change in speeds going down and going up is the same so speeds on the top track are the same.
D : Average speed is greater on track B ( Don’t confuse same speed with same time)

Two balls A and B are released at the same time on an equal length track as shown.

A: Which ball will reach the end of the track first?
B: Does ball B roll faster on the lower section of its track than Ball A rolls on its track?

C: Is the speed gained by by ball B going down the extra dip the same as the speed it loses going up the other side? Does this mean that they speeds of Ball A and ball B will be the same when they reach the end of their track?

D : So overall which ball has the greater average speed?
