A pull or a push applied or exerted on an object is referred to as force. Force is a vector quantity that can cause an object to accelerate, decelerate, or change its direction of motion. It is measured in Newtons and can be exerted through various means such as physical contact, gravity, or electromagnetic fields.

Energy is the ability to do work. It is a fundamental concept in physics that describes the capacity of a system to perform physical or mechanical tasks. It can exist in various forms such as kinetic energy, potential energy, thermal energy, etc. Energy is required to overcome resistance or exert force on an object in order to perform work. Therefore, energy is the correct answer as it directly relates to the ability to do work.

Newton's Second Law (F = ma) defines the relationship between force, mass, and acceleration. Force equals mass multiplied by acceleration, determining an object's motion under applied forces.

Work is said to be done when a force of 1 Newton moves an object of mass 1 gram, 1 meter in the direction of the force. Work is a measure of the energy transfer that occurs when an object is moved by a force applied to it. In this scenario, the force of 1 Newton is applied to move the object of mass 1 gram over a distance of 1 meter, which meets the definition of work.

Conservation of Energy asserts that in a closed system, total energy remains constant. Energy may change forms but is neither created nor destroyed. This principle underlies various physical processes.

Velocity is a vector quantity that describes the rate of an object's motion in a specific direction. It encompasses both speed and direction, distinguishing it from speed, which is scalar. Velocity provides a comprehensive understanding of an object's movement, reflecting both how fast it's moving and the path it's taking.

Newton's second law of motion states that force is directly proportional to acceleration.

Here's a breakdown of the law:

Force is any push or pull that can cause an object to change its motion.

Acceleration is the rate of change of an object's velocity (speed and direction). The greater the acceleration, the faster the change in motion.

The law essentially states that the greater the force applied to an object, the greater the acceleration it will experience. Conversely, a smaller force will result in a smaller acceleration.

Boyle's Law (P1V1 = P2V2) states that, at constant temperature, the volume of a gas is inversely proportional to its pressure. Increasing pressure leads to a decrease in volume and vice versa.

Charles' Law (V1/T1=V2/T2) explains that, at constant pressure, the volume of a gas is directly proportional to its absolute temperature. As temperature rises, volume increases.

Solar energy is derived from the nuclear fusion reactions occurring in the sun, where hydrogen atoms combine to form helium, releasing a tremendous amount of energy. This process powers the sun and provides the Earth with radiant energy in the form of sunlight.
