Does a heavier object always have more inertia than a lighter object?
Inertia is "rotary momentum"; an object's ability to continue spinning when a decelerating force is applied.Just as a heavy object takes more effort to stop from the same speed as a light object, so does a heavy object take more effort to stop from turning at the same speed as a light object.So assuming they are turning at the same angular velocity, the heavier one has a larger inertia. Otherwise, remember that inertia is also proportional to angular velocity.
The force of gravity on a 4kg object is twice that on a 2kg object Why does the 4kg object not fall with twice the accleration?
The reason that a heavier object does not fall faster even though there is more gravitational force on it is because it has more mass, and more energy is required to accelerate the greater mass. A small mass doesn't need a lot of force on it to accelerate it. It's "light" in weight. But a heavier one needs more force on it to accelerate it equally. Want a heavier object to accelerate the same as a lighter one? Apply more force. Gravity does that. Automatically. Think it through and it will lock in.
What are good absorbers of light?
Darker colour indicate better absorption of light. Shiny surface is due to it reflect off the light. When the object to totally dark it is because it absorb all the light and transform to heat. You might want to proof it by placing black object and shiny object in the sun, wait few hour and see which object is hotter.
Does colour affect the amount of heat absorbed?
Darker colors are better absorbers of light which makes them better radiators of heats. Object absorb light which is transferred to heat energy.
Is it possible to lift a object without touching it by mind power?
Yes it is possible, used by the kinetic energy in you, you have to learn to manipulate the kinetic energy in an object. The weight of the object also helps, if you are a beginner start with a light object, and practice, practice, practice! Once you have got that down and you are able to move a small object such as a pen and/or pencil, then try a heavier object, but not way heavier, but just little by little. It's kinda like building muscle in your arms or legs but it's building force in your ability to move your energy.

Which is a better bullet heavy grain or light grain?
No one answer to your question. I shoot light .243 bullets for groundhogs, heavier bullets for deer. All other things being equal, the lighter bullet can be driven faster, but the heavier bullet will retain energy at long range better.
Why doesn't a heavy object accelerate more than a light object when both are freely falling?
Here's the answer, and I love it. Let's assume that heavy objects fall fasterand light objects fall slower, just like everybody wants them to.Follow me now . . .-- Heavier objects fall faster. Lighter objects fall slower.-- Take a heavy object and a light object up to the roof of a tall building.Then take a piece of sticky tape, and stick the light object onto the backof the heavy one. Then walk carefully to the edge of the roof, and dropthe package over the side. As you do that, yell down "Look out below!"-- The heavier object normally falls faster, so it tries to pull the package ahead.The lighter object normally falls slower, so it tries to hold the package back. Soas they fight each other, the package falls at some middle speed, slower thanthe heavy object alone, and faster than the lighter object alone.-- But wait! They're taped together. How is that different from being glued together ?Or melted together ? Or welded together ? Or even inside the same skin ?-- Or even being the same single object ? They could just as well be a single object,one that weighs a little more than the original heavier object.-- But we just agreed that the package falls a little slower than the original heavier object,even though it's heavier than the original heavier object.-- Our orignal assumption . . . that a heavy object falls faster than a lght object . . . leads usdown the garden path to a ridiculous result.That assumption must be wrong.Don't ya just love it !
Why will go down the ramp faster a light object or a heavier one?
a lighter one because it doesn't take long for it to get going but, if you wanna know which one will go farther it would be the heavier one because it has more momentum.
How could you determine if it will take the same time for the lighter and heavier object to reach the ground when dropped at the same height in the same time?
drop a heavy object and a light object from the same height at the same time. time it with a stopwatch, or just watch them.

Should the wood for the catapult be light or heavy?
Heavy, light wood is likely to break or snap under tension.

What is radiation or reflecting light?
When an object is radiating light, it means that the object produces light. When an object is reflecting light, it means that light "bounces off" the surface of that object.
