QUIZ 16 QUESTIONS medium 1 Friction is a force that acts against the direction of the movement. TrueFalse 2 What happens if we apply sufficient force on rigid objects? They can change shape temporarilyThey can breakThey can stop 3 Complete : Speed is how __________ something moves SlowFast 4 Which arrow shows friction? The blue oneThe red one 5 A car takes 3 hours to drive 270 km. What is its speed? 810 km/h90 km/h27 km/h 6 What force makes this ball fall? SpeedThe frictionThe force of gravity 7 When we jump, we land on the ground and don't fly to the space. Why? Because of the speedBecause of the force of frictionBecause of the force of gravity 8 How can we calculate the speed? Dividing the time by the kilometersDividing the kilometers by the km/hDividing the kilometers by the time 9 What is happening in this picture? Gravity makes the ball go more slowly until it stops and fallsGravity make the ball go faster until it stops and fallsFriction makes the ball go more slowly 10 When a ball falls down, gravity make it go faster. True or false? TrueFalse 11 What is friction? It´s the force that reduce the speed of an object in movement until it stopsIt´s the force that attracts the objects towards the surfaceIt´s how fast something moves 12 What is gravity? It´s the force that reduce the speed of an object in movement until it stopsIt´s how fast something movesIt´s the force that attracts the objects towards the surface 13 If we move an object with wheels, what will happen? There will be more friction than if it doesn´t have wheelsThere will be less friction than if it doesn´t have wheelsIt moves easily because of the force of gravity 14 When does the less friction happen : when we walk on snow or on the sand? When we walk on the snowThe same frictionWhen we walk on the sand 15 The woman is swimming against the water. What force is the water doing? Water frictionWater speedWater resistance 16 What force can you see in the picture? Friction and resistanceFrictionResistance A mistake in this Quiz ? Contact the author Commentaires
