Question

Applying Newton's Laws CHAPTERS S-7 5.3 Mass and Weight 16. Suppose you have a jet-powered flying platform that can move straight up and down. For each of the following cases, is your apparent weight equal to, greater than, or less than your true weight? Explain a. You are ascending and speeding up. b. You are descending and speeding up c. You are ascending at a constant speed. d. You are ascending and slowing down c. You are descending and slowing down. 17. The terms "vertical and "horizontal" are frequently used in physics. Give operational defini- tions for these two terms. An operational definition defines a term by how it is measured or de- termined. Your definition sbould apply equally well in a laboratory or on a steep mountainside.

Explanation / Answer

here,

a)

when ascending and speeding up

the accelration is upwards and

the weight is greater than the real weight

b)

when descending and speeding up

the accelration is downwards and

the weight is lesser than the real weight

c)

at constant speed

the weight is same as the real weight

d)

when ascending and speeding down

the accelration is downwards and

the weight is lesser than the real weight

e)

when decending and speeding down

the accelration is upwards and

the weight is greater than the real weight
