Cars, trucks, and buses apply tons of force to bridges each day. Bridge engineers take a lot of physics classes to get their degree. Why would an engineer need to know physics to build a bridge?
The engineer needs to know how to build a bridge that will balance the added force from vehicles traveling on it.
The engineer needs to know how to build a bridge that will unbalance the added force from vehicles traveling on it.
The engineer needs to know how to build a bridge without opposing forces so the bridge will not move.
The engineer needs to know how to build a bridge without friction force so the bridge will not move.
A student performs two investigations of force and acceleration. In the first investigation, she pushes objects with different masses using the same amount of force. In the second investigation, the student pushes objects with the same masses using different amounts of force. The result of both investigations are shown.
Which claim and argument can the student make using her data?
Claim: With a constant force, the acceleration of the objects is proportional to the mass of the objects.
Evidence: The acceleration of the objects increases as the masses of the objects increase.
Claim: With a constant force, the acceleration of the objects is proportional to the mass of the objects.
Evidence: The acceleration of the objects decreases as the masses of the objects decrease.
Claim: With a constant mass, the amount of force applied to the objects is proportional to their acceleration.
Evidence: As the force on the objects increases, the acceleration of the objects increases.
Claim: With a constant mass, the amount of force applied to the objects is proportional to their acceleration.
Evidence: As the force on the objects increases, the acceleration of the objects decreases.

The table below shows the weights of three blocks made of the same material, and the portion of the surface areas of the blocks that are in contact with a level table top.
Which block requires the smallest amount of force to keep it moving slowly?
Block 1, because it has the smallest weight
Block 2, because its weight and surface area are the same
Block 3, because it has the smallest surface area in contact with the table
All three blocks require the same amount of force.
Jose sets up an investigation to determine the effect of force on mass. First, he rolls a 100-gram ball down a ramp and hits the back of a parked 50-gram car. He measures the distance the car moved. Next, he rolls the 100-gram ball down the same ramp and hits the back of a parked 100-gram car. He measures the distance the car moved. Which of the following is most likely to be the result of Jose's experiment?
The 100-gram car moved farther than the 50-gram car.
The 50-gram car moved farther than the 100-gram car.
Both cars moved the same distance.
Neither car moved any distance.
