conservation of energy
The conservation of energy is a fundamental principle in physics stating that energy cannot be created or destroyed, but only converted from one form to another or transferred from one object to another. The total amount of energy within an isolated system remains constant over time
-
Gravitational potential energy (GPE) is the energy stored in an object due to its vertical position or height above a reference point, such as the Earth's surface

newtons laws
-
Newton’s laws explain that acceleration occurs when forces are unbalanced, meaning the net force is non-zero. Acceleration acts in the direction of this resultant force
Constant velocity occurs when frictional or resistive forces exactly balance the driving force, resulting in a zero net force and zero acceleration. According to Newton's First Law, this balanced state causes an object to maintain its current speed and direction
-
Newton’s Third Law states that for every action, there is an equal and opposite reaction. Motion results when an object exerts a force (action) on another, causing the second object to exert an equal force in the opposite direction (reaction). These paired forces, acting on different objects, create acceleration
rminal velocity is reached when air resistance equals weight, creating balanced forces and zero acceleration. It is the maximum, constant speed a falling object achieves
vectors and scalars
Vectors possess both magnitude and a specific direction, such as velocity, force, or displacement
Scalars are physical quantities defined only by magnitude (size), such as speed, mass, or time
vector quantities are force, velocity, displacement and acceleration,
scalar quantities are speed, time, energy and mass
-
acceleration
Acceleration is defined as the rate of change of velocity, calculated as the difference between final velocity and initial velocity divided by time
