Physics

• The second law of motion states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
• Work done = force x distance moved in direction of force
• The third law of motion states that for every action, there is an equal and opposite reaction. This means that whenever an object exerts a force on another object, the second object exerts an equal and opposite force on the first object.
• The first law of motion, also known as the law of inertia, states that an object at rest will stay at rest and an object in motion will stay in motion with the same speed and in the same direction unless acted upon by an external force.
• Inertia is the tendency of an object at rest to remain at rest or an object moving with constant velocity to continue doing so unless acted upon by a resultant force.
• Newton's third law of motion states that when two objects interact, they exert equal and opposite forces on each other.
• Mass is a measure of how much matter an object contains and is measured in kilograms (kg).
• Power (P) = work done / time taken
• Energy can be transferred from one form to another, but energy cannot be created or destroyed.
• Kinetic energy (KE) = 1/2 mv^2
• Energy can be transferred from one place to another or transformed into different forms but cannot be created or destroyed.
• Newton's laws of motion are fundamental principles that describe how objects move and interact with one another.
• A vector quantity has both magnitude (size) and direction, while a scalar quantity only has magnitude.
• Acceleration is the rate at which an object changes its velocity.
• Weight is the gravitational pull acting on an object and is measured in newtons (N) or pounds (lb).
• Inertial frames of reference are non-accelerating or uniformly moving reference frames where Newton's laws apply exactly as they do in an inertial frame of reference at rest relative to the observer.
• An example of a vector quantity is displacement, which has both size and direction, while an example of a scalar quantity is temperature, which does not have a specific direction.

• Work done (W) = force x distance moved
• Work done (W) = force x distance moved
• Work done (W) = force x distance moved

• Gravitational potential energy (GPE) = mass x gravitational field strength x height
• Energy is the ability to do work and can be transferred between different forms such as kinetic energy, potential energy, thermal energy, electrical energy, chemical energy, nuclear energy, elastic energy, gravitational energy, magnetic energy, sound energy, light energy, and electromagnetic radiation.
• Gravitational potential energy is stored energy due to the position of an object relative to Earth's surface.

• Elastic potential energy (EPE) = spring constant x extension squared
• Elastic potential energy (EPE) = spring constant x extension squared
• The equation for kinetic energy is KE = 0.5 x mass x velocity squared.
• The first law states that every object continues in its state of rest or uniform motion unless acted upon by an external force.
