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.

Answer:

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

2. an object’s ability to not change its motion

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

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

5. The force acting on the object must be unbalanced.

The solutions to the 5 questions about balanced and unbalanced forces are;

1) Option B; Two people stand on the same side of a large tire. Both people pull the tire with equal force.

2) Option C; An object’s resistance to a change its motion

3) Option D; The car moves forward, while inertia keeps the balloon in place.

4) Option A; The unbalanced forces of air resistance and gravity slow the airplane and pull it down.

5) Option D; The force acting on the object must be unbalanced.

1) For the 2 forces of people acting on an object to be unbalanced, it means either they are standing on the same side of the object or their forces are unequal. Looking at the options, the most appropriate will be ''Option B'' because they have equal force but yet stand on the same side of the tire.

2) According to newtons' first law of motion which is also called law of inertia, an object will remain at rest or continue in its' current motion except it is acted upon by an external force. Thus, inertia of a body is its' ability to resist change of its' motion. Option C is correct

3) As seen from newton's law of inertia earlier, since the force is only applied to make the car move, the balloon will not move because no force has been directly applied to it to make it move. Thus, option D is correct

4) When a paper plane is thrown in the air, for it to keep being in the air, it needs some type of force from the air to resist the force of gravity acting on it. Now, if the force is not sufficient to resist that of gravity, then it cannot stay up but will fall down. Thus, Option A is correct.

5) Just like in question 4, it is because the force acting on the object is unbalanced. Option D is correct
