Frequently asked questions
What is Topic P2: Forces?
OCR Forces: motion, Newton's laws and forces in action. 48 lessons in 3 subtopics.
How do you calculate distance from speed and time?
Distance is calculated with s = vt, distance = speed × time. The Distance, Displacement and Speed (Part 2/3) notes cover this in full.
What is the formula for kinetic energy?
The kinetic energy formula is Ek = ½mv², where m is mass in kg, v is speed in m/s and kinetic energy is in joules (J). The Kinetic Energy Calculations notes cover this in full.
What is the typical speed of walking, running and cycling?
Typical speeds are about 1.5 m/s for walking, 3 m/s for running and 6 m/s for cycling. The Distance, Displacement and Speed (Part 1/3) notes cover this in full.
What is Newton's second law?
Newton's Second Law states that the acceleration of an object is proportional to the resultant force acting on it and inversely proportional to its mass. The Newton's Second Law: F = ma (Part 1/2) notes cover this in full.
What is the equation for power?
The power equations are P = E/t and P = W/t: power equals energy transferred, or work done, divided by time. The Calculating Power notes cover this in full.
How far away is the Moon?
The Moon orbits about 384,000 km from Earth and takes a whole month to complete one orbit. The Planets, Moons, and Satellites notes cover this in full.
What is the formula for elastic potential energy?
The elastic potential energy formula is Ee = ½ke², where k is the spring constant in N/m, e is the extension in metres and energy is in joules (J). The Elastic Potential Energy Calculations notes cover this in full.
What is the equation for work done?
The formula for work done is W = F × d: work done in joules equals force in newtons times distance moved in metres. The Introducing Work Done notes cover this in full.
