?
What is a scalar?
A scalar is a quantity that has a magnitude only.
1 of 9
What is a vector?
A vector is a quantity with a magnitude and a sense of direction.
2 of 9
What can be represented by a distance-time graph?
How far an object, moving in a straight line, is from a certain point
3 of 9
How can the speed of an object be determined from a distance-time graph?
To find the speed of an object from a distance-time graph, the gradient of the line needs to be determined.
4 of 9
What is the velocity of an object?
Velocity is the speed of an object in a given direction
5 of 9
What is the equation for velocity?
Velocity = Displacement ÷ Time Taken
6 of 9
What is the equation for acceleration?
Acceleration = Change in Velocity ÷ Time Taken
7 of 9
How can the acceleration of an object be calculated?
The acceleration of an object can be calculated by determining the gradient of the line on a velocity-time graph
8 of 9
How can distance travelled by an object be determined?
The distance travelled by an object can be determined by the area underneath the line of a velocity-time graph
