Why does a curve on a distanced graph indicate acceleration?
an increasing distance is traveled during each unit of time
What does acceleration look like on a distance time graph?
On a distance-time graph, acceleration is represented by a curve that shows the slope increasing over time. If the graph is a straight line, it indicates constant speed, while a curved line indicates changing speed. The steeper the curve, the greater the acceleration; if the curve flattens, it suggests a decrease in acceleration. In contrast, if the graph shows a downward curve, it may indicate deceleration.
When a car rounds a curve it's acceleration is zero?
Actually, a car always accelerates on a curve. This is because acceleration, like the velocity it alters, is a vector that has both magnitude and direction. Since taking a curve involves a change of direction, there must be an acceleration to alter the direction; otherwise, the car can only continue straight.
Does the degree of a curve effect acceleration?
Yes, the degree of a curve can affect acceleration. In a curve with a higher degree, the change in direction is sharper, which can lead to higher acceleration as the vehicle needs to adjust its speed to navigate the curve effectively. In contrast, curves with lower degrees may require less acceleration due to their more gradual changes in direction.
How can you find the retardation of a curve in a speed time graph?
Calculate the gradient of the curve which will give the acceleration. Change the sign of the answer to convert acceleration into retardation.
What does this curve indicate?
a horiontal
How do you calculate speed moving around the curve?
To calculate the speed of an object moving around a curve, you can use the centripetal acceleration formula: (a = v^2 / r), where (a) is the centripetal acceleration, (v) is the speed of the object, and (r) is the radius of the curve. To find the speed ((v)), you need to know the radius of the curve and the centripetal acceleration acting on the object.
What is velocity-time curve?
The graph of velocity-time is the acceleration.
When the acceleration is not in a straight line on a graph what does this indicate?
That the force that causes the acceleration is not constant.
What does a bell curve indicate in a trait?
continous variation
Is a car that follows a gentle curve in the road an example of acceleration?
If the vehicle is gaining speed on that gentle curve, yes. Otherwise, no.
What is instantaneous accerlation?
that is acceleration at a particular point in time. If acceleration is changing with time, it is the slope of the velocity vs. time curve.
