Laws

Question 1

Boyle’s Law

Answer 1

For a fixed mass of gas at constant temperature, the pressure is inversely proportional to the volume

Question 2

Newton’s First Law

Answer 2

An object at constant velocity will remain at constant velocity unless acted upon by an external force

Question 3

Newton’s Second Law

Answer 3

The net force on an object is equal to the objects rate of change of Momentum, where the force and change in momentum are in the same direction

Question 4

Newton’s Third Law

Answer 4

When two objects interact, they exert equal and opposite forces on each other

Question 5

Kepler’s First Law

Answer 5

An orbit of a planet is an ellipse with the sun at one of the two foci
