NGSS.MS-PS2-1

Select True or False. Complete mass-energy conversion is a good potential energy source because of the inherent instability of matter.

• True

• False

Tags

NGSS.HS-PS1-8

Select True or False. It is possible for an energy transformation to be 100% efficient under the right conditions.

• True

• False

Tags

NGSS.HS-PS3-3

NGSS.MS-PS2-5

NGSS.MS-PS2-3

Select True or False. When a falling object reaches terminal velocity, its speed drops to zero since the drag caused by air resistance equals the object’s weight. Due to the balanced forces, it stops falling.

• True

• False

Select True or False. Air resistance is usually so small that it can be ignored.

• True

• False

Select True or False. An object’s mass on Jupiter will be different than its mass on Mars.

• True

• False

Select True or False. An 80 kg astronaut floating around in the International Space Station has almost no mass since he is in a “microgravity” environment.

• True

• False
