acceleration is constant though, 9.8m/s^2

Yes, i understand what you mean, but how is acceleration changing?

Thank you for the reply, but I'm not sure how you can calculate the force applied by an object on the ground when it falls from a certain height h. When it's at rest, the force applied is mg, so what about when its in motion?

Weight is defines as the force exerted by the ground on you. F=ma, and m and a are constant. But the weighing machine does not show the same value when you simply stand on it and when you jump on it. So basically my question is, even though force exerted is same, why is there a difference in...

Well, we can't be sure about anything here.

Well, the string theory talks about multiverse, unlike the Big Bang theory. Michio Kaku explains it by comparing it with bubbles. There are many universes. These universes are like bubbles floating around, and when they collide, they form a single bubble- a universe. When a single bubble...

How is it incorrect? To derive that equation, m needs to have a value. 1/0 is not defined.

Nope. Velocity(U1) is not a form of energy. Energy associated with motion is kinetic energy. Therefore K1 ≠ U1. For calculating the speeds of objects in various contexts, you can use the following kinematic formulas: 1) at = v-u 2) S = 0.5at² + ut 3) 2aS = v²-u²

Just as eyes are sensitive to light, the ear is sensitive to the "vibrations" in the medium. These vibrations are sensed by the eardrum, and we perceive it as sound. So, colour and sound are all our perception. On the other hand, vibrations and wavelengths are not.

Yes, I already stated this in the previous reply. The whole "normal force" comes from the concept of Newton's third law of motion. Whatever force you apply downward, the ground's going to exert the same and opposite force upward. This upward force is called "normal". And many people stated more...

Newton's third law of motion states: Every action has an equal and opposite reaction. The weight of an object placed on the plane is the force exerted by it on the plane. So, the plane exerts an equal and opposite force, called the normal. In the case of a slanted plane, the surface is not able...

Well, E = GM/r^2 is applicable only IF the particle has mass, even if its infinitesimally small. Since light's mass is zero, it would not be possible to equate this: >F= (GM¹M₂)/r² >ma/m= GM/r² m=0, so the LHS is not defined. I guess the universal law of gravitation is not applicable to...

Hi, According to Newton, F= (GM¹M₂)/r² Einstein proved that light bends around massive bodies, due to gravity. (because space bends around these bodies) Mass of light = zero, but its being affected by gravity. So, is Newton's equation not universal?

Oh yes, thankyou for the correction :)

To maximize the splash you need to increase the force of the object being dropped by:- 1) Increasing the mass 2) Increasing the acceleration by throwing harder You also need to increase the surface area of the object as to cover the maximum surface of the water. I hope I helped you. Do ask me...
