Velocity at t = 1 10 The graph of this function is given in Figure 6.1. If a line that joins two points lying on the graph of the function it is drawn it is called a chord. We found that when t = 1 and s = 15 the point (1,15) lies on the graph. When t = 1.1 and s ...
Q.2. How is speed different from velocity? Answer: Speed and velocity are kinematic quantities that have unmistakably various definitions. Speed, a scalar quantity, is the rate at which an object covers distance. The average speed is the distance (a scalar quantity) per time proportion. Speed...
Average velocity = (position 2 - position 1)/ (time 2 - time 1) How do you find the average velocity from two points? The y-coordinate of a point in a displacement graph represents position, while the x-coordinate represents time. Average velocity is the slope between two points, which...
Instantaneous velocity from slope The instantaneous velocity at any moment is the slope of the position versus time graph at that moment. In the example, at time t = 4 s the instantaneous velocity is v = 12.5 m/s. At time t = 5 s, the graph shows that the car slows down. At time...
An example of an average rate of change is velocity. Suppose someone drives their vehicle at 50 mph for an hour. This is a rate of change. For every one hour driven, the distance the vehicle has traveled increases by 50 miles. How do you determine average rate of change? To determine ...

Had ss been a linear function of tt, then the two velocities we calculated would have been equal. Here, however, they are different, and we call them average velocities; the train has speeded up from an average velocity of 150 km/h in the first two hours to 160 km/h in the next tw...
A wave has a frequency of 4 Hz and is moving at a velocity of 10 m/s. What is the wavelength of the wave?One year in this prairie dog town, 52 new pups were born and 14 prairie dogs died. What was the population growth rate that year?
Average acceleration is defined as the rate of change of the velocity of the object and is given by the following equation.
