Velocity is the rate of change of an object's position over time, while acceleration is the rate of change of an object's velocity over time. In simpler terms, velocity describes how fast an object is moving, while acceleration describes how quickly the object's speed is changing.
The force on an object can be calculated using Newton's Second Law of Motion, which states that force (F) is equal to mass (m) multiplied by acceleration (a). This can be represented by the equation F = ma.
Kinetic energy is the energy of motion, while potential energy is the energy an object has due to its position or state. For example, a moving ball has kinetic energy, while a ball sitting on a shelf has potential energy due to its position above the ground.
Newton's First Law of Motion states that an object will remain at rest or in motion at a constant velocity unless acted upon by an external force. This is also known as the law of inertia, which describes an object's tendency to resist changes in its state of motion.
Mass is the amount of matter an object contains, while weight is the force of gravity acting on an object's mass. Mass is measured in kilograms (kg), while weight is measured in Newtons (N). On Earth, an object's mass and weight are directly proportional, but on other planets, their weight may differ due to differences in gravitational pull.
