Ch 12 Forces (problemattic)

A girl is sitting in a car without her seat belt on. The car is moving forward and suddenly slams on the brakes. In which direction will she move in a frictionless car?

• to the left

• to the right

• backwards

• forward

• As the strength of the push increases, the distance the car travels would increase.

• As the strength of the push increases, the distance the car travels would decrease.

• As the strength of the push decreases, the distance the car travels would increase.

• There is no relationship to the strength of the push and the distance the car would travel.

• 0 N

• 350 N

• 700 N

• 1,400 N

• The force on both balls was the same; therefore each ball pushes back with the same amount of force.

• The force on both balls was the same; however each ball pushes back with a different amount of force.

• The solid ball pushes back with a greater force.

• The hollow ball pushes back with a greater force.

• The wall pushes with a force of 200 N against the student.

• The wall pushes with a force of 400 N against the student.

• The wall exerts twice as much force as the student.

• The wall exerts no force since it is stationary.

• 
• 
• 
• 

• 10 N

• 11 N

• 12 N

• 13 N

• They are the same because they point toward the objects.

• They are the same because they have the same magnitude.

• They are different because they have different magnitudes.

• They are different because they have different directions.

• 50 N

• 150 N

• 200 N

• 350 N

• downward and to the left

• downward and to the right

• upward and to the left

• upward and to the right
