NEED HELP QUICK (regarding weight and acceleration)

In summary, the statements discussed in the conversation include the use of a spring scale in an accelerating elevator, the net forces on objects dropped from a tower, the relationship between mass and weight, and the effects of a jet-powered platform on apparent weight. It is stated that statements B), C), and D) are false, but the correctness of statements A) and E) is unclear.

Homework Statement


Answer True, False, or Cannot tell to each of the five statements below.
E.g., if the answer to the first statement is `true' and to the rest, `cannot tell', enter TCCCC.

A)You pour 100 g of salt onto a spring scale in an elevator accelerating upward. The scale reads a value greater than 100 g.

B)A 2 kg and a 3 kg ball are dropped from a tower. The net forces on each are the same.

C)Mass and weight describe the same thing, although in different units.

D)You are standing on a jet-powered platform that can move straight up or down. Your apparent weight is greater than your true weight if the platform is descending and speeding up.

E)An astronaut stands on a bathroom scale on the surface of Jupiter; the scale does not read his true weight.


Homework Equations





The Attempt at a Solution


I have tried attempted many solutions (13 out of 15 tries used up). I am fairly sure that B), C), and D) are false. Quick help would be appreciated, time is running short.

What about the ones you're not sure about? What's your reasoning on those?
 

1. What is the relationship between weight and acceleration?

The relationship between weight and acceleration is described by Newton's Second Law of Motion, which states that the force of an object is equal to its mass multiplied by its acceleration. This means that the greater the weight of an object, the more force is needed to accelerate it.

2. How does weight affect an object's acceleration?

Weight directly affects an object's acceleration because it is a measure of the force acting on the object. The greater the weight, the greater the force, and therefore the greater the acceleration. This is why heavier objects require more force to accelerate than lighter objects.

3. Can an object's weight and acceleration be different on different planets?

Yes, an object's weight and acceleration can vary on different planets due to differences in the planet's mass and gravitational pull. The acceleration due to gravity on Earth is 9.8 meters per second squared, but on other planets it can be higher or lower depending on their mass and size.

4. How can I calculate an object's weight and acceleration?

To calculate an object's weight, you can multiply its mass (in kilograms) by the acceleration due to gravity (in meters per second squared). To calculate an object's acceleration, you can divide the force acting on the object by its mass. Both weight and acceleration are measured in the metric system.

5. Does an object's weight change with its acceleration?

No, an object's weight does not change with its acceleration. Weight is a measure of the force acting on an object due to gravity, while acceleration is a measure of the change in an object's velocity over time. These are two separate physical quantities and one does not affect the other.
