A ball is dropped from a tall building. What will most likely happen to the ball?, It will fall to the ground, It will float upward, It will remain in the air, It will move sideways only, Ana pushes a box across the floor. The box slows down after she stops pushing. What force causes this?, Air resistance, Friction, Gravity, Magnetism, Which surface would allow a toy car to move the farthest?, Carpet, Grass, Sandpaper, Smooth tile, A bicycle moves faster downhill even when the rider stops pedaling. What mainly causes this?, Friction, Gravity, Magnetism, Wind, Why is it harder to slide a box across a rough floor than a smooth floor?, Rough surfaces have greater friction, Rough surfaces have less gravity, Smooth surfaces increase weight, Smooth surfaces stop gravity, A student rolls two identical balls down a slope. One ball travels farther. What could explain the difference?, Different amounts of friction acted on the balls., Gravity stopped acting on one ball., One ball had no mass, The balls moved without forces., A book placed on a table does not fall through the table. Which force pulls the book downward?, Friction, Gravity, Magnetism, Tension, A soccer player kicks a ball, but it eventually stops on the grass. What is the best explanation?, Friction opposes the ball's motion., Gravity pushes the ball forward, The ball loses its mass, The ground pulls the ball sideways, Which change would most likely reduce friction between two surfaces?, Adding a lubricant, Making the surfaces rougher, Pressing the surfaces harder, Removing the lubricant, A toy car is pushed on two surfaces. It travels 3 meters on tile but only 1 meter on carpet. What can be inferred?, Carpet produces greater friction than tile, Carpet produces less friction than tile, Gravity is stronger on carpet, The car has more mass on tile, Why do shoes have rough soles?, To increase friction with the ground, To decrease gravity, To make shoes lighter, To reduce body weight, A child jumps upward and then comes back down. Which force causes the child to return to the ground?, Air resistance, Friction, Gravity, Magnetism, Two identical objects are pushed with the same force. Object A moves farther on a smooth surface than Object B on a rough surface. Why?, Object A experiences less friction, Object A has greater gravity, Object B has no friction, Object B has no mass, A marble rolls down a ramp and slows when it reaches a carpet. What happened?, Friction increased and opposed the motion, Gravity disappeared on the carpet, The marble became weightless, The ramp pushed the marble upward, Which situation shows friction being useful?, A car stopping when the brakes are applied, A ball rolling on ice, A sled sliding downhill, A stone falling from a cliff, Which situation shows gravity affecting an object's movement?, A book sliding across a table, A leaf falling from a tree, A toy car stopping on carpet, A shoe gripping a floor, A student wants a toy car to travel farther. Which surface should be chosen?, A smooth wooden board, A rough carpet, A sandy path, A rocky surface, A cyclist applies the brakes while moving. What happens mainly because of friction?, The bicycle slows down, The bicycle becomes weightless, The bicycle moves upward, The bicycle speeds up, Why does a parachute help a person fall more slowly?, It increases air resistance, It increases gravity, It removes friction, It stops the person's mass, A ball is rolled down two ramps with the same height. Ramp A is smooth, while Ramp B is rough. Which ball will likely travel farther?, The ball on Ramp A, The ball on Ramp B, Both balls will stop immediately, Neither ball will move, A heavy box and a light box are pushed across the same floor. Which factor can affect how difficult they are to move?, Friction between the boxes and floor, The color of the boxes, The shape of the floor, The temperature of the boxes, A student puts oil between two moving metal parts. What is the purpose of the oil?, To decrease friction, To increase gravity, To increase weight, To stop movement, A basketball is thrown upward. As it rises, what happens to its upward movement?, It slows because gravity pulls it downward, It speeds up because gravity pushes it forward, It stays at the same speed forever, It stops because friction disappear, Which object would likely experience the greatest friction when pushed?, A box on a rough floor, A ball on a smooth tile, A book on polished wood, A toy car on a smooth table, A student notices that a toy car moves faster when the ramp is made steeper. What is the best inference?, Gravity pulls the car down the steeper ramp more strongly along the slope., Friction completely disappears on the steeper ramp., The car loses its mass as the ramp becomes steeper., Gravity stops acting on the car., Why can people walk without easily slipping on a dry floor?, Friction between the shoes and floor provides grip., Gravity pushes the feet forward, The floor removes body weight, The shoes have no friction, A student tests three surfaces by rolling the same ball on each one. The ball travels 5 m on Surface A, 3 m on B, and 1 m on C. Which surface likely has the greatest friction?, Surface A, Surface B, Surface C, All surfaces have equal friction, A pencil rolls across a table and eventually stops. Which explanation is most accurate?, Friction between the pencil and table opposes its motion., Gravity pushes the pencil forward, The pencil loses its mass, The table removes all forces, A student wants to compare the effects of friction on two toy cars. Which setup is the fairest test?, Use identical cars on different surfaces., Use different cars on different surfaces., Use different cars on the same surface., Use different cars with different pushing forces., A box is difficult to move across a rough floor. Which action would most likely make it easier to move?, Add wheels under the box, Add more weight to the box, Make the floor rougher, Press the box harder against the floor
