Delimiter between question and answer:

Tips:

  • No column headers.
  • Each line maps to a question.
  • If the delimiter is used in a question, the question should be surrounded by double quotes: "My, question","My, answer"
  • The first answer in the multiple choice question must be the correct answer.

Suppose a rightward force of 50 N is applied on a box that has a mass of 15 kg. If the box moved 10m at a constant speed, how much work is done on the object by the 100 N force?
500 Joules
A force of 2 000 N is applied to a 200 kg bicycle. What is the magnitude of acceleration of the car?
10 m/s²
It states that " the acceleration of an object is directly proportional to the net force applied on it and inversely proportional to its mass"
Law of Acceleration
What is the formula to find work?
Work = Force x Displacement or W = Fd
True or False. The more mass an object contains, the higher the inertia.
True
What is the formula to find power?
P = W/t or Power = Work/time
The rate of doing work is called...
Power
What are the three conditions that need to be met before one can say that work is done on an object.
1. Force must be applied on the object. 2. The object must have displacement. 3. The force exerted must move the object toward its own direction.
It is defined as the product of force applied on an object and its displacement.
Work
It states that "for every action, there is an equal but opposite reaction."
Law of Interaction
The law of acceleration is expressed in this formula
F = ma
What are the three laws of motion?
Law of Inertia, Law of Interaction, and Law of Acceleration
It is a force that opposes the motion of an object.
Friction
It is a vector quantity that may or may not produce a change in the motion.
