Mia uses a ramp to roll two toy cars at different speeds into a block of clay.
One car rolls fast, and one car rolls slow.
What is most likely to happen when the cars hit the clay?
A. The faster car will make a bigger dent in the clay.
B. The slower car will go farther than the faster car.
C. Both cars will make the same dent.
D. The clay will move away before they hit it.
A. The faster car will make a bigger dent in the clay.
A student slides a book across a carpet and then across a smooth table.
The book moves more slowly on the carpet than on the table.
What causes the book to slow down more on the carpet?
A. The carpet is slippery.
B. The carpet causes more friction.
C. The table is heavier than the carpet.
D. The book gets tired of moving.
B. The carpet causes more friction.
Students tested how far a toy car rolls down different ramps: one made of sandpaper, one of cardboard, and one of smooth plastic. They noticed:
The car rolled farthest on the smooth plastic ramp.
The car slowed down the most on the sandpaper ramp.
The class wanted to design a new ramp that helps the car go fast and far.Which surface should they use, and why?
A. Sandpaper, because it creates more friction and slows the car down.
B. Cardboard, because it’s the softest and helps the car stop quickly.
C. Smooth plastic, because it causes less friction and helps the car go faster.
D. Carpet, because it is rough and makes the car bounce.
C. Smooth plastic, because it causes less friction and helps the car go faster.
1. Two bowling balls are rolling toward each other. What will happen when they collide?
A. The bowling balls will pull on each other.
B. The bowling balls will push on each other.
C. The white ball will keep moving forward. The black ball will stop.
D. The black ball will keep moving forward. The white ball will stop.
B. The bowling balls will push on each other.
A student uses a ruler to push a toy car across different surfaces: carpet, pebble, and smooth tile.
The student records how far the car moves each time.
Surface Distance Moved
Carpet 10 cm
Pebbles 6 cm
Smooth Tile 20 cm
Which conclusion can the student make from this investigation?
A. The toy car moves the farthest on rough surfaces.
B. Pulling the toy car will always make it stop.
C. The smoother the surface, the farther the car moves when pushed.
D. The toy car moves the same distance no matter the surface.
C. The smoother the surface, the farther the car moves when pushed.
Students rolled toy cars down ramps at different heights into balls of clay to see how much the clay changed shape. They recorded their results in the table below:
Ramp Height Speed of car Size of dent in clay
Low slow Small dent
Medium medium Medium dent
High fast Big dent
What is the best conclusion students can make from this investigation?
A. Higher ramps make toy cars lighter.
B. Slower speeds cause smaller dents.
C. A stronger push makes the car go slower and causes a bigger dent.
D. The clay changes shape the same no matter the speed.
B. Slower speeds cause smaller dents.
A student rubs a wooden block on two different surfaces: sandpaper and smooth paper.
The block feels warmer after rubbing it on the sandpaper.
What is the cause of the block getting warmer?
A. The color of the block changed.
B. The sandpaper made the block colder.
C. The friction from the sandpaper produced heat.
D. The smooth paper was heavier than the sandpaper.
C. The friction from the sandpaper produced heat.
A class tested how a toy car moved across different surfaces: smooth tile, carpet, and sandpaper.
Their results are shown below:
Surface of track Distance car moved
tile 9 in
wood 7 in
gravel 3 in
Then the teacher asked: "How could we design a track that helps the car move the farthest?"
Which surface should the class choose and why?
A. Sandpaper, because it has the most friction and makes the car stop quickly.
B. Carpet, because it makes the car move at a medium speed.
C. Smooth tile, because it has the least friction and helps the car go the farthest.
D. Sandpaper, because it makes the car heat up the most.
C. Smooth tile, because it has the least friction and helps the car go the farthest.
