Motion Revision Quiz questions

Round 1 1.Which of the following is a scalar measurement? displacement distance velocity

Round 1 2.Convert 1250mm into m 1250mm = 1.25m

Round 1 3.The symbol ‘u’ in a motion equation represents: final velocity, uccaleration, initial velocity

Round 1 4.Give one the name of the quantity that this definition describes: ‘The rate of change of velocity.’ acceleration

Round 1 5.Look at the graph below. Is the object undergoing constant velocity acceleration or deceleration?

Round 2 6.Newton’s second law explains the relationship between force, mass and acceleration. Write the equation that shows this relationship. F = ma

Round 2 7.What does the area under a velocity / time graph represent? acceleration average velocity displacement

Round 2 8.If a person runs 100m in 10s, then what is their average velocity for the run? v av = s/t = 100/10 = 10ms -1

Round 2 9.If a car goes from a stationary start to 3ms -1 in 6s, then what is their average acceleration? a=(v-u)/t=(3-0)/6=3/6=0.5ms -2

Round 2 10.If an object is dropped from a classroom window, then what will be it’s velocity after 1s? 9.8ms -1

Round 3 11.Newton’s 2 nd Law tells us that a force will change an object’s motion. If a book is sitting on your desk it experiences weight, friction etc but does not move. Why? Because there is no net force- all the forces balance each other.

Round 3 12.Newton’s 1 st Law says that objects keep moving in a straight line until a force acts on them. Why, when you throw a rock does it eventually stop moving? Forces are experienced by the rock (air resistance, friction, gravity etc) which change it’s motion.

Round 3 13.What is the name of the quantity that results from the multiplication of mass and velocity? momentum, kinetic energy, or massive velocity.

Round 3 14.If a car has a momentum of 300Ns and it hits a stationary child with a mass of 40kg, then what will be the total momentum after the collision? 300, 340 or 7.5Ns

Round 3 15.Which of the following graphs best describe the acceleration experienced by an object that is thrown straight up, stops and then falls back to the ground?

Round 3 15.
