• A. Strong Nuclear Force

• B. Weak Nuclear Force

• C. Electromagnetic Force

• D. Gravitational Force

Why are the fundamental forces dubbed as "fundamental"?

• A. It is because these fundamental forces are the forces that exists in the entirety of the universe.

• B. It is because these forces are the easiest to compute when applied mathematically.

• C. It is because these forces have a value of either zero or one.

• D. None of these is the correct answer.

Which of the following must be present in order for us to say that an object is experiencing motion?

• B. The object must have a change in location.

• C. The object must have moved near or far from its reference point.

• D. All of these are correct.

What do we call the force that took place when the source of the force and the receiver of the force are in physical contact with each other?

• A. Non-Contact Force

• B. Balanced Force

• C. Contact Force

• D. Unbalanced Force.

An object fell to the ground due to the planet's gravity. Which of the following forces can best describe this?

• A. Balanced and contact force

• B. Unbalanced and contact force

• C. Balanced and non-contact force

• D. Unbalanced and non-contact force.

Who is considered to have consolidated all the different principles concerning force and motion?

• B. Effect of mass to the movement of the object

• C. Effect of net external force to the movement of the object.

• D. Effect of force on a moving object.

Which of the following statements describe how force affects moving objects?

• A. When force is applied to moving objects, the object will stop from moving.

• B. When force is applied to moving objects, the object will change its direction of movement.
