How Do You Describe A Distance Time Graph? A distance-time graph shows how far an object has travelled in a given time. It is a simple line graph that denotes distance versus time findings on the graph. Distance is plotted on the Y-axis. Time is plotted on the X-axis. How do you describe a motion
How Do You Explain Acceleration? Acceleration, rate at which velocity changes with time, in terms of both speed and direction. A point or an object moving in a straight line is accelerated if it speeds up or slows down. … Acceleration is defined as the change in the velocity vector in a time interval, divided
Does Work Done Depend On Speed? No, work done by force at any instant does not depend upon the velocity at that instant. Work is dependent on the force and displacement. Two identical ball bearings in contact with each other and resting on a frictionless table are hit head-on by another ball bearing of the
How Fast Can An Object Fall In Water? Near the surface of the Earth, any object falling freely will have an acceleration of about 9.8 metres per second squared (m/s 2). Objects falling through a fluid eventually reach terminal velocity . How fast does an object fall through water? Near the surface of the Earth,
How Do You Find The Height Of A Free Falling Object? The distance the object falls, or height, h, is 1/2 gravity x the square of the time falling. How do you measure height in free fall motion? Choose how long the object is falling. In this example, we will use the time of 8
How Do You Know If An Object Has Moved? When is an object in motion? An object is in motion if its distance relative to another object is changing. To tell if an object is moving, you use a reference point. If an object’s distance from another object [reference point] is changing. How would you
How Many Seconds Until The Ball Hits The Ground? The ball will hit the ground 6.06 seconds after thrown. How many seconds does it take the ball to hit the ground? It takes three seconds for the ball to hit the ground. How do you find the time when the ball hits the ground? Determine
How Do You Find Acceleration Without Time? If the acceleration is constant, it is possible to find acceleration without time if we have the initial and final velocity of the object as well as the amount of displacement. The formula v2=u2+2as where v is the final velocity, u is the initial velocity, a is the
How Is Train Speed Calculated? Problems to calculate the motion or speed of train: 1. Find the time taken by a train 150 m long, running at a speed of 90 km/hr in crossing the pole. Therefore, time taken by the train to cross the pole = 150 m/25m/sec = 6 seconds. How do you
How Do You Find Final Velocity? Final velocity (v) of an object equals initial velocity (u) of that object plus acceleration (a) of the object times the elapsed time (t) from u to v. Use standard gravity, a = 9.80665 m/s2, for equations involving the Earth’s gravitational force as the acceleration rate of an object.
