Flashcards do conjunto (12)
- 1What is a scalar?A quantity with magnitude only
- 2What is a vector?A quantity which has magnitude and an associated direction
- 3How do you find the speed of an object on a distance time graph?You calculate the gradient of the line
- 4What is the velocity of an object?Its speed in a given direction
- 5How do you determine the distance travelled by an object on a velocity time graph?Calculate the area under the line
- 6Whenever two objects interact, the forces they exert on each other are 1. Unequal and parallel 2. Equal and parallel 3. Equal and opposite 4. Unequal and opposite3. Equal and opposite
- 7What is a resultant force?A single force that has the same effect on the motion as the original forces all acting together
- 8If the resultant force acting on a stationary object is zero, what will happen?The object will remain stationary
- 9If the resultant force acting on a stationary object is not zero, what will happen?The object will accelerate in the direction of the resultant force
- 10If the resultant force acting on a moving object is zero, what will happen?The object will continue at the same speed in the same direction
- 11If the resultant force acting on a moving object is not zero, what will happen?The object will accelerate in the direction of the resultant force
- 12What is the conservation of momentum?The idea that the total momentum before an event is equal to the total momentum after the event
