What does a straight line with a negative slope mean?
A negative slope means that two variables are negatively related; that is, when x increases, y decreases, and when x decreases, y increases. Graphically, a negative slope means that as the line on the line graph moves from left to right, the line falls.
What does it mean when velocity has a negative slope?
Negative velocity and positive slope,: object is slowing down. If the V-T line has a negative slope, the object is undergoing acceleration in the negative direction.
What does a negative slope on a distance time graph mean?
In position and time graphs, the slope of line indicates the velocity. Therefore negative slope of a position-time graph actually indicates negative velocity. Negative velocity is defined as the velocity of the object moving in an opposite direction.
Can a distance graph be negative?
Nope. Distance is a non-directional quantity. During a motion, it can only either be kept unchanged or increased. Therefore, within a particular period, the distance-time graph is always either constant or increasing in the absence of decreasing and a negative slope.
Can you have a negative value on a distance-time graph?
Usually, a line with a negative gradient would indicate motion going backwards. This cannot be shown on a distance-time graph.
Can a distance vs time graph have a negative slope?
Yes, when the velocity of the obect is begative.
What does negative distance mean?
When, if ever, does negative distance mean something? When you have a defined origin and a given direction. For example: Height above sea level. You can measure the distance of a point from that plane, the elevation of your landscape. If it dips below zero, that point has negative height (=distance).
How do you find the total distance on a graph?
Calculating the distance travelled
- Calculate the total distance travelled by the object – its motion is represented by the velocity-time graph below.
- Here, the distance travelled can be found by calculating the total area of the shaded sections below the line.
- ½ × base × height.
- ½ × 4 × 8 = 16 m 2
- (10 – 4) × 8 = 48 m 2
