Frequently asked questions
What is Topic P6: Global challenges?
OCR Combined Science Physics global-challenges content. 17 lessons in 2 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 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 the equation for acceleration?
The equation for acceleration is a = Δv/t, where Δv is the change in velocity (final velocity − initial velocity) in m/s and t is the time taken in s. The Acceleration, Velocity-Time Graphs and Terminal Velocity (Part 1/3) notes cover this in full.
What are fossil fuels?
Fossil fuels are energy sources formed from dead organisms buried and compressed over millions of years. The Energy Resources: An Overview notes cover this in full.
What is velocity?
Velocity is the speed of an object in a given direction, measured in metres per second (m/s) in a specified direction. The Distance, Displacement and Speed (Part 3/3) notes cover this in full.
What is terminal velocity?
Terminal velocity is the maximum constant velocity reached by a falling object when drag force equals weight, giving zero resultant force and zero acceleration. The Acceleration, Velocity-Time Graphs and Terminal Velocity (Part 3/3) notes cover this in full.
How do you calculate average speed?
Average speed is total distance travelled divided by total time taken. The Distance, Displacement and Speed (Part 3/3) notes cover this in full.
Why is acceleration measured in m/s²?
Acceleration is measured in m/s² because it is velocity (m/s) divided by time (s), giving m/s/s. The Acceleration, Velocity-Time Graphs and Terminal Velocity (Part 1/3) notes cover this in full.
