It is convenient for someone to take barrow to do shopping. But in the situation of 2 or even more people, the barrow will distract the person from shopping who takes care of the barrow. He is restricted or set alone. He has to pay so much attention to the barrow that it may reduce the enthusiasm of shopping. However the shopping basket will not affect so much.

Long-term, the cart also can be part of an expedited check out system that decreases congestion during the check out process (Media Cart, 2010). Consumers scan items as they put them into their carts and directly into bags. At the end of their shopping experience, they move the cart onto the scale to check for accuracy and for additional items, before they pay and leave; this process could save money by reducing customer service personnel.

doesn't work, then you use force or action (the big stick) to achieve your goal. In this particular

15) A cart starts from rest and accelerates at 4.0 m/s2 for 5.0 s, then maintain that velocity for 10 s, and then decelerates at the rate of 2.0 m/s2 for 4.0 s. What is the final speed of the car?

Introduction During this lab you will become more familiar with the concepts of torque. The purpose of this lab is to determine if the rotational equilibrium condition, Στ = 0, holds experimentally. Equipment Meter stick (1) - no metal ends Fulcrum (1) Clamps (4) Weight Hanger (1) Mass Set (1) Digital Scale (1)

Newton?s second law can be explained with the equation, A=F/M or F=MA, where A=Acceleration, F=Force, and M=Mass. In normal words, Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object). You can use this formula to see how much force is needed to move certain objects. Lets say Mike?s car is about 1,000 kg. He pushes it at .06 m/s/s. The equation would be F=1,000(.05). The answer is F=50 Newtons (the SI unit for Force). If Bob is trying to move a van, which was about 2,000 kg at the same acceleration, then he would need to use twice the force that Mike had to because Bob?s car is 2,000 kg and Mike?s is 1,000 kg.

As a first instinct, the driver tries to slam on the trolley’s brakes to avoid hitting any of the workmen. Unfortunately, the brakes on the trolley do not work. Thus, the driver is left facing this situation: should he continue going straight or should he quickly turn the trolley to the right? If he stays straight, he will continue hurdling towards the five helpless workmen, inevitably hitting and killing all five of them. If he flips to switch to turn the trolley right, the driver will undoubtedly hit the lone workman and take his life (Thomson 1395).

About half way up the mountain the speed and momentum will increase as you approach the top of the hill. Then out of nowhere a large amount of friction will begin to slow your cart down just before you drop inside Storm Mountain. Finally you will reach the very top of the hill that takes you into the mountain where potential energy is at its greatest. Suddenly you will fall into a gaping hole of the mountain and rush down a massive hill while you experience a state of freefall, velocity and terminal velocity. All the energy from the first hill will then shoot you up a second, slightly smaller hill while you will experience high amounts of kinetic energy. The ride will slowly decrease in speed while you wrap around a center point. As you go around the two loops you will experience both centripetal acceleration and centripetal force. The ride will then begin to pick up speed and acceleration and go around a slight bend when a sudden break stops the movement of the cart so you can hear the sounds of booming thunder and crashing lighting. That is when Newton's 1st law would comes into play as the sudden breaks stop the

Does it take more force to slide an object across a surface if there is a high value of μ or a low one? Explain your answer

To test Newton’s seconds law if whether changing the mass or the force affects the acceleration of an object or a trolley in this case to increase or decrease.

In this experiment,we applied Newton`s first law of motion. It descripes the external force as the sum of all external force applied to the object, which equals zero in equilirbium. As we have seen in the experiment, to reach equilibrium all the forces applied on an object shoud cancel each other out and total force reaches zero.Using different forces and weights we were able to reach equilibruim ineach trial of this

railroad tracks or cut in between the carts that is called trespassing and you will get fined. So I

In our third lab, we experimented with the cohesive forces of surface tension. Water and pepper were combined. Soap was applied into a hole in a boat. The boat had a keyhole slit extending from the hole. The soap reduced the surface tension. The molecules spread out in all directions from the soap, but they could only travel through the keyhole slit in our boat. They traveled backward, but a force pushed forwards, propelling our boat forward. Newton’s Third Law states for every action there is an equal and opposite reaction. So, for the molecules escaping behind the boat, an equal and opposite force pushed the boat forwards.

‘’It consisted of huge Frisbee-shaped robots that could be steered via a grid of floor magnets. The robots picked up the warehouse rack containing the item in the customer order and delivered it to the operator. He picked the item from the rack; scanned its barcode to verify that it was correct; and put the item in a cardboard box with that customer’s shipping label’’ (Forbes, 2013)

The forces that are involve with the experiments are basically focused on the concurrent forces. The experiment also allows us to develop the condition of balancing or arranging the angles both sides on a force table. This laboratory experiment allows us to take the mathematical abstraction of a vector to make it tangible as possible. This experiment will look into two ways of
