Physics: Matter, Energy, and Interactions Quiz

Physics Overview

• Physics is the scientific study of matter, energy, and the interactions between them, encompassing a wide range of phenomena in the natural world.
• It explores fundamental concepts such as force, energy, mass, and charge, contributing to our understanding of the universe.

Unit of Force

• The unit of force in the International System of Units (SI) is the Newton (N).
• One Newton is defined as the force required to accelerate a one-kilogram mass by one meter per second squared (1 N = 1 kg·m/s²).

Electric Charge

• The SI unit of electric charge is the Coulomb (C).
• One Coulomb is equivalent to the amount of charge transported by a constant current of one ampere in one second (1 C = 1 A·s).

Types of Energy

• Kinetic energy is the type of energy associated with the motion and position of an object.
• The kinetic energy of an object is calculated using the formula KE = 1/2 mv², where m represents mass and v represents velocity.
