In which situation are unbalanced forces acting on an object?(1 point) Two people stand on opposite sides of a large tire. Both people pull the tire with equal force.

Two people stand on the same side of a large tire. Both people pull the tire with equal force.

Two people stand on opposite sides of a large tire. Both people push the tire with equal force.

Two people stand on the same side of a large tire. One person pushes the tire and the other pulls the tire with equal force.

What is inertia?(1 point)

the motion of an object

the speed and direction of an object in motion

an object’s resistance to a change its motion

a force that acts on an object at rest

A balloon floats inside a stopped car. When the car starts moving forward, the balloon appears to move backward relative to the car. Which statement best explains this observation?(1 point)

The motion of the car creates an unbalanced backward force on the balloon.

The force of inertia on the balloon balances the force from the motion of the car.

Inertia prevents the force of the car from acting on the balloon.

The car moves forward, while inertia keeps the balloon in place.

Which statement best explains why a paper airplane eventually falls to the ground?(1 point)

The unbalanced forces of air resistance and gravity slow the airplane and pull it down.

Inertia slows the airplane and pulls it down.

Inertia prevents new forces from acting on the airplane to keep it up.

The force from throwing the airplane loses strength as the airplane moves.
According to Newton’s first law, what must be true of a force for it to stop an object in motion?(1 point)

The force acting on the object must be stronger than other forces acting on the object.

The force acting on the object must be stronger than the inertia of the object.

The force acting on the object must be opposite of the direction of movement.

The force acting on the object must be unbalanced.
