Force And Motion Vocabulary Quiz

Explanation
Force is the correct answer because it refers to a push or a pull on matter. Force is a vector quantity that can cause an object to accelerate, decelerate, or change its direction of motion. It is measured in Newtons (N) and is responsible for any change in the state of motion of an object. In this context, force is the most appropriate term to describe the concept of a push or a pull on matter.

Explanation
Unbalanced force refers to a force that causes a change in motion. When there is an unbalanced force acting on an object, it will accelerate or decelerate, causing a change in its velocity. In contrast, balanced forces do not cause any change in motion as they cancel each other out. Momentum is a property of a moving object and is not directly related to causing a change in motion. Inertia, on the other hand, is the tendency of an object to resist changes in its motion, but it does not cause the change itself.

Explanation
Balanced forces are the forces that do not cause changes in motion. When the forces acting on an object are balanced, their magnitudes and directions cancel each other out, resulting in a net force of zero. As a result, the object remains at rest or continues to move at a constant velocity. In other words, the forces are in equilibrium, and there is no acceleration or change in motion.

Explanation
The net force is the sum of all the forces acting on an object. It takes into account both the magnitude and direction of each individual force. When all the forces are added together, the resulting net force determines the object's overall motion or acceleration. Inertia, acceleration, and mass are all related to the object's response to the net force, but they do not represent the sum of the forces themselves.

Explanation
An object tends to keep in motion when in motion because of inertia. Inertia is the resistance of an object to changes in its motion. According to Newton's first law of motion, an object in motion will continue to stay in motion with the same speed and direction unless acted upon by an external force. This is due to the object's inertia, which causes it to resist any changes in its state of motion.

Explanation
Mass is the measure of the amount of matter in an object. It represents the total number of atoms and molecules present in the object. Unlike weight, which is influenced by gravity, mass remains constant regardless of the location. Volume, on the other hand, is the amount of space occupied by an object and is not directly related to the amount of matter present. Temperature is a measure of the average kinetic energy of particles in an object and does not directly indicate the amount of matter.

Explanation
Newton's 2nd Law states that the acceleration of an object is directly proportional to the net force applied to it and inversely proportional to its mass. This means that when a force is applied to an object, it will accelerate in the direction of the force, and the acceleration will be greater if the force is larger or the mass is smaller. Therefore, the correct answer is "Force, Mass, and Acceleration."

Explanation
The correct answer is Mass X Acceleration because according to Newton's second law of motion, force is directly proportional to the mass of an object and the acceleration it experiences. This means that the force acting on an object is equal to the product of its mass and acceleration. So, the greater the mass of an object or the greater the acceleration it experiences, the greater the force acting on it.

Explanation
Friction is the correct answer because it is a force that acts in opposition to motion. When two surfaces are in contact, friction arises and opposes the relative motion between them. It acts in the opposite direction to the applied force, making it harder for objects to move or slide. Friction is present in various everyday situations, such as when walking, driving a car, or using a pencil on paper. It is an essential force that helps us maintain control and stability in our interactions with the physical world.
