What is the area under a power time graph?
2. When a graph represents a physical quantity, the area under the graph can have an important contextual meaning; in the case of the graph of power vs time, the area under the graph gives the energy generated by the solar panels.
What is the correct unit for the area under a force time graph?
The area under a force-time graph is force multiplied by time, which is a quantity called impulse. Impulse is equal to the change in momentum of an object.
What is the physical meaning of the area under a force displacement graph?
A force-displacement graph will have force (in N) on the vertical axis and displacement (in m) on the horizontal axis. The area of the graph is = Fs. This quantity represents the work done on the object. Use the area under the graph to find the work done by the force.
What does the slope of displacement and time graph represent?
A sloping line on a displacement-time graph shows that the object is moving. In a displacement-time graph, the slope or gradient of the line, is equal to the velocity of the object. The steeper the line (and the greater the gradient) the faster the object is moving.
What is the slope of the chord on displacement time graph?
l Slope of the chord drawn to displacement (distance)-time graph gives us the average velocity (average speed) over the time interval to which the chord corresponds to. l From the position-time graph, we can determine the sign of acceleration but its value can’t be determined from the position-time graph.
What are 3 common units of speed?
The most common units of speed are metres per second (m/s), kilometres per hour (km/h) and miles per hour (mph).
What is the function of a speedometer?
Speedometer, instrument that indicates the speed of a vehicle, usually combined with a device known as an odometer that records the distance traveled. Speedometer gauge in a car. A speedometer.
Does distance vary directly with time?
For example, speed and distance traveled vary directly for a given time. If you travel at 4 mph (6.5 kph) for three hours, you go 12 mi (19.5 km), but at 6 mph (9.5 kph) you go 18 mi (28.5 km) in three hours. The ratio of distance to speed is always 3 in this case.
When the speed is constant time is directly proportional to distance?
If an object travels at a constant speed, then the distance traveled is directly proportional to the time spent traveling, with the speed being the constant of proportionality. The circumference of a circle is directly proportional to its diameter, with the constant of proportionality equal to π.
