What is the law of universal gravitation?

The law of universal gravitation is a scientific principle that describes the force of gravity between two objects. It states that every point mass attracts every other point mass by a force acting along the line intersecting both points. This force is proportional to the product of their masses and inversely proportional to the square of the distance between them.

Potential energy is the stored energy an object has due to its position or configuration, while kinetic energy is the energy an object possesses when it is in motion. Potential energy can be converted into kinetic energy, and vice versa. For example, a stretched rubber band has potential energy that is converted into kinetic energy when it is released.

Torque is a measure of the rotational force that causes an object to rotate. It is calculated by multiplying the force applied to the object by the distance from the axis of rotation to the point where the force is applied. Torque is often represented by the symbol τ (tau).

The scientific method is a systematic process used to develop and test scientific knowledge. It involves making observations, formulating hypotheses, predicting outcomes, testing hypotheses through experimentation, and drawing conclusions based on the results. This process helps to ensure that scientific knowledge is based on evidence and is reliable.

Simple interest is calculated as a percentage of the principal amount, while compound interest is calculated as a percentage of the principal amount plus any accrued interest. Compound interest can result in a larger total amount over time due to the interest being added to the principal amount, allowing it to earn interest on interest.
