Momentum & Impulse

Momentum & Impulse - A Level Physics Quiz

QuestionAnswer
What is the symbol for momentum? p
Define momentum = mass x velocity
Define change in momentum = final momentum - intial momentum
Newton's 2nd law (in terms of acceleration) RESULTANT force acting on an object is proportional to its acceleration; the acceleration takes place in the DIRECTION of the resultant force
Newton's 2nd law (in terms of momentum) the rate of change of momentum of an object is proportional to the RESULTANT force acting on it; the change in momentum takes place in the DIRECTION of the resultant force
If F is proportional to ma, what is F equal to? F = k ma
What is the value of k in F = k ma 1
how do we define the newton so that k = 1 in F = k ma? 1 newton is the force that provides a mass of 1 kilogram with an acceleration of 1 metre per second squared
Is momentum a scalar or a vector? vector
What is the unit of momentum? kilogram metre per second
Define Newton's 2nd law in terms of acceleration force = mass x acceleration
Define Newton's 2nd law in terms of rate of change of momentum force = mass x rate of change of momentum
Give a symbol formula for impulse with 'Ft' as the subject of the equation Ft = m(v-u) or Ft = mv - mu
What is the 'preferred' unit of impulse? Ns

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.
