Why does an object such as a cannonball appear to fall toward Earth rather than Earth falling toward the cannonball?
The cannonball and Earth both fall towards each other due to gravity. However, the Earth's much larger mass results in the cannonball appearing to fall towards the Earth because the Earth's gravitational force is much stronger. This is in accordance with Newton's law of universal gravitation.

What happens to the color black when light hits it?
When light hits a black object, it is absorbed by the object's surface molecules rather than being reflected. This absorption of light energy causes the object to appear black to our eyes.
What type of object absorbs light rays?
A black object absorbs light rays by converting them into heat energy rather than reflecting or transmitting them. These objects appear black because they absorb most of the visible light spectrum.
Why must one keep the falling distance constant when testing the effect of mass on the thermal energy on a falling object?
Keeping the falling distance constant ensures that the object experiences the same amount of gravitational potential energy regardless of its mass. This allows for a fair comparison of the effect of mass on the thermal energy generated upon impact, as any differences observed can be attributed to changes in mass rather than changes in potential energy.
Does a catapult create a free fall?
No, a catapult does not create free fall. A catapult uses tension to launch an object, causing it to follow a curved trajectory rather than free falling straight down.
When a perceived object changes position but you still see it?
This phenomenon is known as motion-induced blindness, where a stationary object may appear to disappear or become less visible when surrounded by moving elements. It is thought to be caused by the brain's visual processing system giving more attention to the motion of the surrounding objects, rather than the stationary object itself.
How will an object size and mass affect its terminal velocity?
The terminal velocity of a falling object depends upon its aerodynamics (which is to say, its shape) rather than its size and mass.
What happens to the color black when light hits it?
When light hits a black object, it is absorbed by the object's surface molecules rather than being reflected. This absorption of light energy causes the object to appear black to our eyes.
Which object weighs approximately 1 newton?
The weight of an average apple is around one Newton. Rather appropriate when you consider that it was a falling apple that made Newton think about gravity.

Why do black cars get hotter in the sun?
Cars that appear black look that way because they are absorbing the light falling on them rather than reflecting it. Since they are absorbing more light energy than lighter colored cars, they get hotter.
If an object absorbs red and green light outside in the daylight what color will it look to your eyes?
If the object absorbs red and green light, it will mainly reflect or transmit the blue light, so it will appear blue to your eyes. This is because the color we perceive is based on the light that is not absorbed by the object, but rather reflected or transmitted back to our eyes.
Why might scientists measure the weight of an object rather than the weight of an object?
The mass of an object does not change , but its weight can vary.

Do black color reflect any color?
A true black will not reflect any light of any colour.
