A student is pushing a toy car down a ramp. If the student places the toy car on the ramp again and increases the force used to push the toy car, what will happen?

• The kinetic energy will decrease, and the toy car will go faster.

• The kinetic energy will increase, and the toy car will go faster.

• The potential energy will increase, and the toy car will go slower.

• The potential energy will decrease, and the toy car will go slower.

A paper airplane is flying toward a fan at a constant speed. If the fan is turned on, what is the best explanation of how the motion of the paper airplane will change?

• The paper airplane will fly faster toward the fan because of a balanced force.

• The paper airplane will fly faster toward the fan because of an unbalanced force.

• The paper airplane will fly slower toward the fan because of a balanced force.

• The paper airplane will fly slower toward the fan because of an unbalanced force.

A group of students was challenged to construct a boat that could transport 10 mL of corn syrup across a small, plastic swimming pool. Which QUESTION will best help the students design their boat?

• What force is needed to push the boat across the length of the pool?

• What boat shape is needed to lower the density of the boat and the corn syrup?

• What is the mass of the boat and the corn syrup?

• What is the distance from one point of the pool to the point on the exact opposite side?

Will is doing an experiment. He wants to find out how objects with different masses are affected when he pushes them with the same amount of force. To do his experiment, he has a cart and several weights he can put in the cart. By putting more weights in the cart, Will can make the cart more massive. By putting fewer weights, he can make the cart less massive. Will has a stopwatch, so he can measure how fast the cart goes. If he plans to study the relationship between the mass of the cart and its speed when pushed with the same amount of force, what else does Will need?

• a way to change the force pushing on the cart

• a way to change the kind of surface the cart travels on

• a way to push the cart with the same force every time

• a way to change the mass of the cart
