Mechanics Vocabulary

What is the definition of force in physics?

• Force is the same as energy in physics

• Force is a constant value in all situations

• Force is any interaction that, when unopposed, will change the motion of an object.

• Force is only applicable to living organisms

What are the different types of friction?

• Dynamic friction, thermal friction, electrical friction

• Static friction, kinetic friction, rolling friction, and fluid friction

• Surface friction, internal friction, external friction

• Solid friction, air friction, magnetic friction

Explain the concept of potential energy.

• Potential energy is the energy that an object possesses due to its position or condition. It is stored energy that has the potential to do work.

• Potential energy is the energy that an object possesses due to its temperature. It is thermal energy.

• Potential energy is the energy that an object possesses due to its color or shape. It is aesthetic energy.

• Potential energy is the energy that an object possesses due to its motion. It is kinetic energy.

What is the first law of thermodynamics?

• Energy can only be transformed into one specific form

• Energy can be created out of nothing

• Energy cannot be created or destroyed, only transformed from one form to another.

• Energy can be destroyed completely

Define physics and its significance in the field of science.

• Physics is the study of human behavior

• Physics is the study of matter, energy, and the interactions between them. It is significant in the field of science because it provides the fundamental principles and laws that govern the natural world, and it forms the basis for understanding other branches of science such as chemistry, biology, and astronomy.

• Physics has no significance in the field of science

• Physics is only relevant in the field of chemistry

What is the formula to calculate force?

• F = m + a

• F = m / a

• F = m * a

• F = m ^ a

How does friction affect the motion of an object?

• Friction has no effect on the motion of an object

• Friction speeds up the motion of an object

• Friction slows down the motion of an object and can eventually bring it to a stop.

• Friction causes the object to change direction

Explain the concept of kinetic energy.

• Kinetic energy is the energy an object possesses due to its position

• Kinetic energy is the energy an object possesses due to its rest

• Kinetic energy is the energy an object possesses due to its motion, and it is calculated using the formula KE = 0.5 * m * v^2.

• Kinetic energy is the energy an object possesses due to its potential energy

What are the three laws of thermodynamics?

• The first law states that energy can be created or destroyed

• 1. The first law states that energy cannot be created or destroyed, only transformed from one form to another. 2. The second law states that the entropy of any isolated system always increases. 3. The third law states that as the temperature of a system approaches absolute zero, the entropy of the system approaches a minimum value.

• The third law states that as the temperature of a system approaches absolute zero, the entropy of the system approaches a maximum value

• The second law states that the entropy of any isolated system always decreases

How is energy transferred in the process of conduction?

• Energy is transferred through the emission of light

• Energy is transferred through the movement of fluid particles

• Energy is transferred through direct contact between particles in a material.

• Energy is transferred through electromagnetic waves
