PhysicsForces and MotionGCSEAQA Created by: MattJGCreated on: 02-03-17 21:40 Does a parachute increase or decrease the frictional force acting on the parachutist, or does it have no effect on this force? increase 1 of 10 An object falling through a fluid originally accelerates due to what force? gravity 2 of 10 What name is given to the steady speed of a falling object when the downwards and upwards forces on it are balanced? terminalvelocity 3 of 10 What is the resultant force on an object that has reached its terminal velocity? 0 4 of 10 True or false? Acceleration due to gravity (g) is the same for any object at a given point on the Earth's surface. True 5 of 10 True or false? Acceleration due to gravity (g) will be the same on the top of a mountain as it is down a mineshaft. False 6 of 10 True or false? Acceleration due to gravity (g) is unaffected by atmospheric changes. True 7 of 10 A sky-diver is falling through the Earth's atmosphere at terminal speed. What is happening to her kinetic energy? Same 8 of 10 A sky-diver is falling through the Earth's atmosphere at terminal speed. What is happening to her gravitational potential energy? Decreasing 9 of 10 A plane travelling at 100m/s accelerates at 5m/s² for a distance of 125m. What is the final velocity of the plane? 106 10 of 10
