QuestionAnswer
The resultant 200 Newton, 45° has an equilibrant with magnitude _____. Group of answer choices 200 Newton 100 Newton 50 Newton 20 Newton ✅ 200 Newton
The resultant 200 Newton in the first quadrant has an equilibrant in what quadrant of the Cartesian Coordinate System? Group of answer choices III I II IV ✅ Correct answer: III
"What is the weight if the mass is 50" Express your final answer as whole number (apply rounding) ✅ 490 N
Given a vector of 662 kmph, 188 degrees. Which is the magnitude of the vector? The angle does not affect the magnitude. ✅ Answer: 662 km/h
Given a vector of 743 kmph, 215 degrees. Which is the direction of the vector? The direction of the vector is simply the angle that accompanies its magnitude. Given: Magnitude: 743 km/h Direction: 215° ✅ Answer: 215°
Given 3 vectors below, find the magnitude of their resultant. 48 N east 48 N south 48 N west The east and west vectors cancel each other: Horizontal component: 48−48=0 Vertical component: −48 Resultant vector = 48 N south The magnitude of the resultant is: ✅ 48 N
Given 3 vectors below, find the direction of their resultant. 1000 N east 1000 N south 1000 N west Group of answer choices south east north west The east and west vectors cancel each other out: Horizontal component = 1000−1000=0 Vertical component = 1000 N south Therefore, the resultant points south. ✅ Correct answer: south
What is the percent difference if the equilibrant is equal to the resultant, in terms of their magnitude? Group of answer choices 0 100 50 1000 Since their magnitudes are equal: Resultant magnitude = Equilibrant magnitude Difference in magnitude = 0% ✅ Correct answer: 0
Using the force table, the three vectors were balanced by placing counterweights on the fourth unused string and locating the appropriate angle or direction. These counterweights on the fourth position represents what vector? equilibrant resultant sca ✅ Correct answer: equilibrant
The tip-tail method is also called _____ method. Group of answer choices polygon method experimental method parallelogram method ✅ Correct answer: polygon method

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
