P.1.1 EOG Review #16

The chart below shows four identical wagons loaded with different amounts of bricks.

If the same amount of effort is applied to all four identical wagons, why would Wagon W move farthest?

• It has the least amount of mass, affecting its motion.

• It has the least amount of speed, affecting its motion.

• It has the greatest amount of gravity, affecting its motion.

• It has the greatest amount of friction, affecting its motion.

Ana is pushing a wheelbarrow of rocks. She stops and unloads half of the rocks. How will this effect the force needed to move the wheelbarrow?

• Gravity is increased, making the wheelbarrow easier to move.

• Gravity is decreased, making the wheelbarrow harder to move.

• Friction is increased, making the wheelbarrow harder to move.

• Mass is decreased, making the wheelbarrow easier to move.

Katie was pulling a sled with her puppy in it. Katie’s sister then got into the sled with the puppy. How would the sled’s speed most likely change after Katie’s sister got into the sled?

• The speed would increase due to the change in mass.

• The speed would decrease due to the change in mass.

• The speed would increase due to the change in friction.

• The speed would decrease due to the change in gravity.

Billy rolls a toy truck filled with marbles across the kitchen floor. He then dumps the marbles before rolling it back to his starting location. How would the speed of the truck most likely change on the way back?

• The speed would increase due to friction.

• The speed would increase due to a change in mass.

• The speed would decrease due to a change in mass.

• The speed would decrease due to a change in gravity.

Chris attaches a sheet of sandpaper to the top of his skateboard. How does this sandpaper most likely affect Chris’s skateboarding?

• It protects the skateboard from any damage.

• It allows Chris to steer the skateboard in a variety of directions.

• It reduces the effect gravity has on the skateboard as he moves down the ramp.

• It increases friction between the skateboard and Chris’s foot to keep him from slipping.

Four cubes made of different materials are moving down a plastic slide. Which cube would experience the greatest amount of friction?

• the cube made of ice

• the cube made of sandpaper

• the cube made of smooth plastic

• the cube made of polished stone

Four different students take turns pushing a large, heavy ball on the school parking lot. What is the BEST way to determine which student used the most force to push the ball?

• compare the sizes of the students

• compare the ages of the students

• compare the distances that the ball rolled

• compare the number of times the ball was rolled

In a science lab, students measured how long it took for a block to slide down a ramp.

What were the students comparing in this experiment?

• the amount of frictional force acting on the block

• the amount of gravitational force acting on the block

• the amount of frictional force acting on the ramp

• the amount of gravitational force acting on the ramp

Two students are investigating kinetic energy using a wooden board and a tennis ball. One student holds the end of the board, and the other student places the tennis ball on it. The tennis ball rolls along the board to the ground.

What could be done by the student holding the board in order to increase the kinetic energy of the tennis ball as it rolls down the board?

• tilt the board to the left

• tilt the board to the right

• raise the end of the board

• lower the end of the board
