Force and Motion Test 4th grade

A girl pushes a grocery cart. Her father begins to help her push the cart in the same direction. How will the force applied by the father MOST LIKELY affect the motion of the cart?

• It will cause the cart to speed up and change direction.

• It will cause the cart to slow down and change direction.

• It will cause the cart to speed up, but not change direction.

• It will cause the cart to slow down, but not change direction.

Two teams compete in a game of tug-of-war, pulling in two different directions on a rope. Every person on both teams pulls with the same force, and the rope does not move. What type of force is this?

• unbalanced

• balanced

• motion

• velocity

Which of these is the BEST definition of force?

• how quickly an object's position is changing

• how quickly an object's direction is changing

• something that cannot make an object move

• something that can change an objects motion

Megan put two cars on the floor. The toy cars are the same size, mass, and weight. Megan puts a different amount of force on each car. After Megan pushes the cars, Car A is moving slower than Car B. The force that Megan put on the Car A was most likely:

• a frictional force

• a gravitational force

• larger than the force on Car B

• Smaller than the force on Car B
