It is important to understand what can be concluded if a block is constantly moving left at a constant velocity. The answer may surprise you! There are two possible conclusions that one could make if this were the case: either the block has an infinite mass or it has no mass. It is not possible for there to be any other conclusion from these premises, unless of course some new information comes to light in the future.
To figure out if the block has an infinite mass, one would need to find the distance between two lines. This can be done by dividing the velocity of the block into its acceleration, which will tell you how far it has been able to move in a given time. The distance between two lines is measured from one point on the line that intersects with another line, and if this distance is infinite then there would be an infinite mass for this block. If they are not parallel, however, then we know that the blocks have no infinitesimal mass because their accelerations are different- meaning there must be some force acting upon them (gravity). In order to measure where these forces could come from without finding any new information , one would need to find the moment of inertia.
The equation for calculating this is as follows: I=m*r^g/l, where m is the mass and r is the radius from which we measure distance. If you take a look at any object in your surroundings, it won’t be surprising if you notice that they have an infinite value when solving this equation- meaning there are forces present on these objects acting upon them like gravity or friction. These forces can be calculated by taking what’s known as “the net force” (or Fnet) and measuring how much work has been done over time; no matter what type of force it may be, all those factors will correspond with each other through Newtonian mechanics because they all have an equal magnitude.
One can conclude that if a block is moving to the left at a constant velocity, they are not acted upon by any forces and so it’s moving with no work done- leading one to wonder how this could be happening. The answer lies in inertia: when objects move in different directions, they must apply force on themselves continuously; therefore, there will always be some resistance present due to friction or gravity depending on what direction it is going and you’ll never get something for nothing just because of its constant velocity.
It might also now seem like these blocks are being pushed around without actually doing anything! A great example of this phenomenon was seen through Galileo’s experiments where he would have two people push each other on a ball from opposite directions. If they both push hard enough, the ball will stay at rest and if one pushes with more force than the other then it would move in that direction- but still without any work done!
This is because when objects are at equilibrium, there’s no net external torque on them which means their acceleration doesn’t change. The forces acting on these blocks must be balanced so if you’re pushing to the left as fast as I am moving to the right or vice versa, we’ll appear stationary relative to one another since our speeds cancel out and we don’t have any kinetic energy in this block system (and thus can’t do work). However, if someone was able to provide an unbalanced force like applying some pressure to the right side of this system, then that part of the block would move without any work done!
Block One: if a block is moving to the left at a constant velocity, what can one conclude?
If they both push hard enough, the ball will stay at rest and if one pushes with more force than the other then it would move in that direction- but still without any work done!
Block Two: This is because when objects are at equilibrium…
If you’re pushing to the left as fast as I am moving to the right or vice versa, we’ll appear stationary relative to one another since our speeds cancel out and we don’t have any kinetic energy in this block system (and thus our momentum is zero).
If you’re pushing to the left as fast as I am moving to the right or vice versa, we’ll appear stationary relative to one another since our speeds cancel out and we don’t have any kinetic energy in this block system (and thus our momentum is zero).
Block Three: But if there’s a net force…
The ball will move in whichever direction with no work done. You can send it straight across by just applying pressure on both sides of the table! In other words, if there are two different forces acting at once then they produce what scientists call “work.” This happens when an object moves from point A to point B while resisting a force that wants it to stay put.
