【题目】物理考试要求英文翻译(a)define displacement, speed, velocity and acceleration.*(b) use graphical methods to represent displacement, speed, velocity and acceleration.*(c) find displacement from the area undera velocity-time graph.* (d) use the slope of a displacement-time graph to find ...
The everyday experience of acceleration is in a vehicle. You step on the accelerator, and the car speeds up as increasing force is applied to the drive train by the engine. But deceleration is also acceleration - the velocity is changing. If you take your foot off the accelerator, the for...
1 (a)(i) Define velocity.[1](ii) Distinguish between speed and velocity..[2](b) A car of mass 1500kg moves along a straight, horizontal road. The variation with time t of the velocity v for the car is shown in Fig. 1.1.40-30v/ms-12010-1.02.03.04.05.06.0t/s Fig.1.1The ...
Represent graphically the displacement, velocity and acceleration against time for a particle performing linear SHM starting from the positive extreme position. State the conclusions. View Solution If a body starts rotating from rest due to a torque of 1.5 Nm, then its kinetic energy after it compl...
The angular acceleration of a particle moving along a circular path with uniform speed is View Solution A particle moves with uniform speed in a circular path the angle between instantaneous velocity and acceleration is View Solution View Solution ...
The S.I. unit of acceleration is m/s2. - Velocity measured in meters/second, and time in seconds. ∴ meter / second X second = ms / s square Velocity and speed are not same - velocity is a vector quantity i.e., it has both magnitude and direction. ...
Define velocity and acceleration in terms of position and time. Differentiate between the instantaneous quantities and the averaged quantities. How to find the average velocity and speed for a position-time graph? a) Find the instantaneous velocity at 0.5 s. b) Find the instantaneous velocity at ...
(a) Defining equation is .Where is the acceleration of the system is the angular frequency / angular velocity of system is the displacement of the system from the equilibrium(b)(i)(ii) Explanation of negative sign (any one of the following)- Since net force and displacement are in opposite...
the previous run and because it does not modify the cached information. First clear the simulation run cache for the new reference frame to instantiate in the browser. The Clear command is the first command, from the left, in the Output Grapher toolbar and is enabled when a simulation runs...
Each particle piece M3,1 has 2∞vvu intervals along each of 3 velocity dimensions and each interval has ∞ivu increments. Multiplying these together after taking it to the number of dimensions power gives the number of universes within M3,1 . Number of universes in π ( ) ( )6 ∞ p ...
