Mock Formulas Flashcards
What is the formula for kinetic energy?
Kinetic energy = 0.5 * mass * velocity^2 = 1/2 * m * v^2
Kinetic energy is the energy possessed by an object due to its motion.
What is the formula for gravitational potential energy (GPE)?
GPE = mass * gravitational field strength * height = mgh
GPE is the energy an object possesses due to its position in a gravitational field.
What is the formula for power?
Power = work done / time taken = w/t
Power measures the rate at which work is done or energy is transferred.
What is the formula for efficiency?
Efficiency = (useful energy output / total energy input) * 100
Efficiency is a measure of how much input energy is converted to useful output energy.
What is the formula for weight?
Weight = mass * gravitational field strength = m * g
Weight is the force exerted by gravity on an object.
What is the formula for work done?
Work done = force * distance travelled = F * s
Work done is the energy transferred when a force is applied over a distance.
What is the formula for force?
Force = spring constant * extension = k * e
Force is an interaction that changes the motion of an object.
What is the formula for distance travelled?
Distance = speed * time = v * t
Distance travelled is the total movement of an object in a specific direction.
What is the formula for acceleration?
Acceleration = (final velocity - initial velocity) / time
Acceleration is the rate of change of velocity of an object.
What is the formula for momentum?
Momentum = mass * velocity = m * v
Momentum is the quantity of motion an object has and is dependent on its mass and velocity.
What is the formula for resultant force?
Resultant force = mass x acceleration = m * a
F = ma
