Torque is a measure that is based on the force that is acting on one system causing the object to rotate at its known axis of rotation. The formula to find torque is T=F*R*Sin
2)Point of axis is important because direction of force is perpendicular to that of the axis.
3)Of the two laws the first is law of conservation of energy which explains that energy cannot be created nor destroyed in an isolated system. The second law is the law of thermodynamics states that the entropy of any isolated system always increase.

1. Torque is the twisting that tends to cause rotation. The equation is T=FxRxSIN(THETA)

2. The point of axis is important because it determines how much force is needed

3. The three laws of thermodynamics

1. Law of Conservation of Energy (energy can’t be created or destroyed)

2. Entropy always increases

3. Entropy of a system approaches a constant value as temperature approaches absolute zero

4. T= 2N* 0.45m= 0.9 Nm

5. T=  5N * 0.35m= 1.75 Nm

6. T= 4N * 0.1m= 0.4 Nm

7. D= 1.75Nm/0.35m

1. Torque is a measure of how much a force acting on an object causes it to rotate. T= f x r x sin(theta)
2. The point of axis is important since it allows us to see where the object will rotate.
3. The three laws of thermodynamics: Law of Entropy (entropy in a system is always increasing), Law of Conservation (energy cannot be created or destroyed in a system), and the third law of thermodynamics states that the entropy of a system approaches a constant as temperature goes toward absolute zero.

1. A torque is a a measure of how much a force acting on an object causes that object to rotate.
T = F * r * sin(theta)
2. The point of axis is important because it determines how much a person needs to input to move the object.
3. The three laws of thermodynamics are :
1-  states that energy cannot be created or destroyed in an isolated system.
2- the entropy of any isolated system always increases
3- states that the entropy of a system approaches a constant value as the temperature approaches absolute zero.

1. Torque isa measure of how much a force acting on an object causes that object to rotate. Formula: T= r F sin(theta)
2. The point of axis is important because its the direction of the force in which it must rotate at.

1. Torque is a measure of how much a force acting on an object causes that object to rotate. T = r x F = r Fsin(feta).
2.  The distance from the point of axis to the point where the force acts determines how much force one needs to input to move the object.
3. The three laws of thermodynamics are the Law of Conservation of Energy, Law of Entropy, and that the entropy of a system approaches a constant value as the temperature approaches absolute zero.

1. Torque is a measure of how much a force acting on an object causes an object to rotate. T = r x f.
2. The point of axis is important because the direction of the force is perpendicular from the point of axis.
3. The first law of thermodynamics states that energy cannot be created nor destroyed. The second law of thermodynamics states that in an isolated system, entropy always increases. The third law states that the entropy of a perfect crystal at absolute zero is 0.
