Explanation
The correct answer is "Mass". Mass is a property of matter that measures its resistance to acceleration. It is a measure of the number of atoms in an object and is measured in kilograms. Mass is related to inertia, which is the tendency of an object to keep moving in a straight line at a constant velocity. The greater the mass of an object, the greater its inertia and resistance to changes in motion.

Explanation
The correct answer is "A force perpendicular to the surface on which an object sits." This is known as the normal force. It is the force exerted by a surface to support the weight of an object resting on it. It acts perpendicular to the surface and prevents the object from sinking into or falling through the surface. The normal force is equal in magnitude and opposite in direction to the force exerted by the object on the surface, according to Newton's third law of motion.

• L.

A force perpendicular to the surface on which an object sits

I. A state in which opposing forces or influences are balanced
Explanation
Equilibrium is a state in which opposing forces or influences are balanced. This means that there is no net force acting on an object, resulting in no change in its motion. In other words, if an object is at rest, it will remain at rest, and if it is in motion, it will continue moving at a constant velocity. This concept is also known as the Law of Inertia, which states that an object will maintain its state of motion unless acted upon by an external force.

By drawing arrows to represent the forces and labeling them with their magnitudes and directions, the free body diagram provides a clear picture of the forces involved in a particular scenario. This allows for a better analysis of the forces and their impact on the object's motion and equilibrium.

Explanation
The given correct answer states that friction force is the force that opposes the motion of an object. Friction is a force that acts in the opposite direction to the motion of an object when it is in contact with another surface. It arises due to the interaction between the surfaces and can vary depending on factors such as the roughness of the surfaces and the force pressing them together. Friction plays a crucial role in everyday life, as it allows us to walk, drive vehicles, and grip objects. It is essential to overcome friction in certain situations, such as lubricating moving parts or reducing drag in vehicles, to optimize efficiency.

This means that an object will continue in its state of motion (either at rest or moving with a constant velocity) unless acted upon by an external force. Inertia is directly related to the mass of an object, with larger masses having greater inertia.

Explanation
The correct answer is the sum of all forces acting on an object. This means that when multiple forces are applied to an object, the net force is the vector sum of all those forces. It takes into account both the magnitude and direction of each force to determine the overall effect on the object's motion. By calculating the net force, we can determine whether the forces are balanced (resulting in no change in motion) or unbalanced (resulting in acceleration or deceleration).
