Forces

QuestionAnswer
What is a Force? A Force is a push or pull.
What does the term 'balanced forces' mean? The net force equals zero. Therefore the objects motion is not affected.
What does the term 'unbalanced forces' mean? The net force is not zero. Therefore the objects will accelerate (or decelerate).
Which of the following forces are 'contact forces'? Friction, Weight, Air Resistance, Magnetism, Applied force (push), Electrical , Spring force, Tension , Upthrust/Trust The contact forces are: Friction, Tension (Pull), Air Resistance , Applied Force (Push) , Spring Force (Twist), Upthrust/Thrust
What are the three effects forces can have on an object? Squash, Stretch and Move
What is the resultant force? 15N <--- O -> 5N 10N to the left
What is the resultant force? 150N <--- O -> 50N 100N to the left
What is the resultant force? 25N <- O ----> 100N 75N to the right
What is the resultant force? 30N <-- O ----> 80N 50N to the right
What happens if an object is stretched too far? It deforms inelestically (it breaks and can no longer return to it's original shape)
Weight = _________ x __________? Weight = mass x gravitational field strength
What is the SI unit for Force? Newtons, N
What is weight? Weight is a force due to gravity.
What is mass? Mass is the amount of matter ('stuff') which an object is made up from.

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.
