Physics 0.0 / 5 ? PhysicsRevisionGCSEAQA Created by: Ryan PhellipyCreated on: 24-11-16 13:08 What is the word equation for acceleration? Acceleration= change in velocity / change in time = m/s^2 1 of 8 What's the equation for speed? Speed= distance/ time =m/s 2 of 8 What's the equation for force ? Force (N) = mass ( kg) * Acceleration ( m/s^2) 3 of 8 What is the thinking distance? The distance travelled by the vehivle in the time it takes the driver to react. 4 of 8 What is braking distance ? Braking distance is the distance travelled by the vehicle during the time the braking 5 of 8 What's Hooke's law? The extension of a spring is directly proportional to the force applied. 6 of 8 What's the work done calculation ? WD ( joules)= force applied (newtons) * distance object moves ( metres) 7 of 8 What are the units of : acceleration, mass, force, weight, momentum, kinetiv energy, gravitational potential energy and work done? Acceleration (m/s^2), mass ( kg), force ( N), momentum( kgm/s), kinetic energy ( J), G.P.E (N), Work done ( J) 8 of 8
