Newtonian Mechanics and Forces

Volume is the measure of the amount of three-dimensional space an object occupies. Mass measures the amount of matter, and weight measures the force of gravity on that mass.

As an arrow is pulled back in a bow, work is done to deform the bow, which stores energy as elastic potential energy. Therefore, the potential energy increases.

Gravity is the fundamental force of attraction that pulls objects toward the center of a massive body like the Earth. The other options are either fictional or unrelated to this specific gravitational pull.

Weight is defined as the force exerted on an object due to gravity. Mass is the amount of matter in an object and is constant regardless of gravity.

Weight is the measure of the force of gravity acting on an object's mass. Unlike mass, weight changes depending on the gravitational field strength.

Newton's 3rd Law states that for every action, there is an equal and opposite reaction, meaning forces always exist in pairs.

Newton's 1st Law (Law of Inertia) states that an object at rest will remain at rest unless acted upon by an external, unbalanced force.

The 1st Law dictates that an object's velocity remains constant unless an unbalanced force changes its state of motion.

Newton's 2nd Law defines the relationship between force, mass, and acceleration, typically expressed as F = ma.

Newton's 3rd Law states that for every action, there is an equal and opposite reaction.

Inertia is the property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force.

Newton's 1st Law is commonly referred to as the Law of Inertia because it describes the tendency of objects to resist changes in their state of motion.

Newton's 1st Law states that an object at rest stays at rest and an object in motion stays in motion unless acted upon by an unbalanced force.

Gravity is the force that attracts objects toward the center of the Earth. It is responsible for keeping us on the ground.

In physics, a force is defined as any push or pull that can change the motion or shape of an object.
