Physics (P1)

• Most kids hate learning GSCE energy names.
• Magnetic energy is a type of energy.
• Kinetic energy is a type of energy.
• Heat energy is a type of energy.
• Light energy is a type of energy.
• Gravitational potential energy is a type of energy.
• Sound energy is a type of energy.
• Chemical energy is a type of energy.
• Elastic potential energy is a type of energy.
• Electric potential energy is a type of energy.
• Nuclear energy is a type of energy.
• Work done (J) = Force (n) x Distance (m) is a formula for energy.
• GPE (J) =mass (kg) X g x height(m) is a formula for energy.
• Kinetic energy (ek)(J) = ½ mass(kg) x (speed)2 (v^2) is a formula for energy.
• Mass = 2ek/v^2.
• Volciticity= square root of (2Ek/mass) is a formula for energy.
• Elastic energy= ½ ke^2 is a formula for energy.
• Force = spring constant (k) x extension (e) is a formula for energy.
• Energy efficiency = useful energy output/ total energy output is a formula for energy.
• Work done= when force causes an object to move through a distance, work is done to the object is a formula for energy.
• Energy can be never created or destroyed only transferred is a law known as the Conservation of Energy Law.
• Total energy, Useful energy, Wasteful energy are different types of energy.
• Gravitational Potential Energy (GPE) (J) = mass (kg) x acceleration due to gravity (g) x height (m)
• Acceleration due to gravity (g) = 10
• To find extension, calculate increased distance - original distance
• Energy efficiency can be expressed as a decimal or percentage, but it cannot exceed 1 or 100%
