It is false. The slope of a straight line on a position-time graph is the average velocity. Slope = y2-y1/x2-x1. On a position-time graph, y is the position (d), and x is the time (t). So y2-y1 = df-di = displacement, and x2-x1 = tf-ti = time interval.

Average velocity = displacement/time interval = df-di/tf-ti

Is Acceleration is the magnitude of average velocity true or false?

False


Is it true or false Acceleration is the magnitude of average velocity?

False. Acceleration is the rate of change of velocity. Average velocity is the total displacement divided by the total time.


Velocity is the slope of a displacement vs time graph true or false?

False. Velocity is the slope of a position vs time graph, not a displacement vs time graph. Displacement vs time graphs show how an object's position changes over time, while velocity represents the rate of change of position.


Average acceleration is the slope of a velocity vs time graph A True B False?

False. Average acceleration is calculated as the change in velocity divided by the time interval over which the change occurs, not from the slope of a velocity vs. time graph.


Does equation of exchange equal money stock m-velocity of circulation-v equals average price of transactions p-timest the number of transactions?

it is false .the answer is money stock times velocity of circulations equals average price of transactions times the number of transactions. mv=pt


True or false a velocity of 32.2 ft per hour is a linear velocity?

It need not be true if 32.2 ft per hour is the average velocity.


Is Distance the magnitude of average velocity?

No, distance and average velocity are not the same. Distance is the total amount covered by an object irrespective of direction, while average velocity is the displacement of an object divided by the time taken, taking direction into account.


Is the total distance traveled divided by the constant speed is the average speed true or false?

In physics, total distance/TIME is average speed, so this is false. Velocity should be switched out with TIME.


Is Velocity is the product of a force and the time during which the force acts true or false?

False. Velocity is the result of applying force to an object over time, but it is not calculated by simply multiplying force and time. Velocity is the rate of change of an object's position with respect to time.


Is acceleration equal to the initial velocity minus the final velocity and then divided by time?

No, acceleration is calculated as the change in velocity divided by time. It is the rate at which the velocity of an object changes. Mathematically, acceleration is represented as (final velocity - initial velocity) / time.


True or false velocity is the slope of the displacement vs. time graph?

It depends on whether it is a positive slope or a negative slope. If the velocity increases as time goes on, yes the particle is accelerating. If the velocity decreases as time goes on, it is decelerating.


True or false a velocity of 50 rad per min is a linear velocity?

False.
