Why the distances Travelled by the trolleys can be used as a measure of their velocities?
Listen to the sound of the collisions against the barrier/buffer. The trolleys hit the wooden planks at different times, because one trolley moves more slowly than the other one (different velocities). These distances are used as a measure of the velocities of the two trolleys in this experiment. 7.
Why can distance be used as a measure of velocity?
Velocity is the measure of the amount of distance an object covers in a given amount of time. Here’s a word equation that expresses the relationship between distance, velocity and time: Velocity equals distance travelled divided by the time it takes to get there.
What determines the distance Travelled by a moving object?
1, we learned that when the velocity of a moving object’s velocity is constant (and positive), the area under the velocity curve over an interval of time tells us the distance the object traveled.
What is the relationship between momentum and distance?
Linear momentum (p) is defined as the mass (m) of an object multiplied by the velocity (v) of that object: p = m*v. With a bit of a simplification, angular momentum (L) is defined as the distance of the object from a rotation axis multiplied by the linear momentum: L = r*p or L = mvr.
What violates the law of conservation of momentum?
Conservation of momentum is violated only when the net external force is not zero. But another larger system can always be considered in which momentum is conserved by simply including the source of the external force.
What do you mean by law of conservation of momentum?
conservation of momentum, general law of physics according to which the quantity called momentum that characterizes motion never changes in an isolated collection of objects; that is, the total momentum of a system remains constant.
How does distance affect speed?
The speed is directly proportional to distance travelled. The definition says,the measure of speed is distance travelled by a body of uniform mass per unit time henceforth,speed is directly proportional to the distance travelled by the body.
Is distance proportional to velocity?
The average velocity is calculated as the distance travelled, d divided by the time taken, t. Notice that for a constant time interval, if I double V (travel twice as fast), the distance travelled will also double. We can say that the velocity is directly proportional to the distance travelled.
Why is distance and displacement important?
Distance traveled is needed to calculate average speed (i.e., total distance over a period of time). Displacement is needed to find the final position of an object; it tells not only the distance from the starting position, but also the net direction of travel.
In which condition is the distance Travelled by an object zero?
Answer: The displacement of a moving object in a given interval is zero i.e., the object comes back to its initial position in the given time (displacement is the shortest distance between the initial and final position of an object).
Work, Force, and Distance Work is the use of force to move an object. It is directly related to both the force applied to the object and the distance the object moves. Work can be calculated with this equation: Work = Force x Distance.
