Secondly, gravity (in the Newtonian paradigm) is a force between two masses. If two astronauts are in orbit together and experience no other forces, they will eventually be pulled together by their mutual gravitation for each other. There is no minimum mass for gravity’s action.

His theory predicted that objects with great mass deform space around them, causing light to deflect into them. According to theory, the reason mass is proportional to gravity is because everything with mass emits tiny particles called gravitons. These gravitons are responsible for gravitational attraction.

Any object having some mass will attract another object having mass. this is because of gravity. When two objects ahving some mass are separated by some distance then force of gravity acts between them and tends to keep them close that means it is always attractive in nature.

Mass is intrinsic to matter, but weight is the force of gravity on that mass. Remember, F=ma. The acceleration due to gravity does not depend on the mass of the object falling, but the force it feels, and thus the object’s weight, does.

Mass doesn’t affect speed directly. It determines how quickly an object can change speed (accelerate) under the action of a given force. Lighter objects can do with weaker force to change speed by a given amount in a given amount of time.

As the angle increases, the component of force parallel to the incline increases and the component of force perpendicular to the incline decreases. It is the parallel component of the weight vector that causes the acceleration. Thus, accelerations are greater at greater angles of incline.

Gravity is the force that causes things to fall to earth. When you drop a ball (or anything) it falls down. Gravity causes everything to fall at the same speed. This is why balls that weigh different amounts hit the ground at the same time.

The correct answer is the last one: the two will hit the ground at the exact same time. This is because gravity accelerates all objects equally, even if one object is heavier than the other. The watermelon also has a lower acceleration because it is heavier and the egg the opposite.

The reason the crumpled paper hits the ground first is because of air resistance. A crumpled piece of paper has less surface area than an piece of paper that is not crumpled. More surface area means more air resistance.

A flatter piece of paper invites more air to push against it, while the crumpled sheet is does not. All this says, however, is that they fall at different speeds due to the different magnitudes of air resistance acting on them. Not due to “lesser” gravitational acceleration.

Unbalanced forces cause a change in motion, speed, and/or direction. When two forces act in the same direction on an object, the net force is equal to the sum of the two forces. When two unequal forces act in opposite directions on an object, the net force is the difference of the two forces.
