When a pair of balanced forces acts on an object, the net force that results is
greater in size than both forces combined.
equal in size to one of the forces.
greater in size than one of the forces.
equal to zero.
When an unbalanced force acts on an object,
the object’s motion does not change.
the mass of the object changes.
the object accelerates.
the inertia of the object increases.
Newton’s first law of motion states that if a moving object is acted on by balanced forces, it will
remain in motion at a constant velocity
change its momentum.
eventually come to a stop.

Slamming on the brakes in a moving car makes a passenger move forward against his or her seat belt because
the passenger has the inertia to keep moving forward
the passenger is being pushed by the seats of the car
the passenger is better able to stop themselves in this manner
the passenger has an equal and opposite force supporting their weight
You are holding a bowl of hot soup while standing in the kitchen. As you begin to move, the soup spills out of the bowl. This happens because
the soup spilled because of air resistance
if you had traveled faster this wouldn't have happened
the soup wanted to stay where it was, but you moved the bowl
the soup and the bowl act as one body with the same velocity
Why do you lean towards the left when a car turns right?
because of your inertia
because of the car's acceleration
because of gravity
