      Sourav Chowhan First of all this, I want to say that all are an example of a scientific phenomenon called Friction.
      Friction is the resistance to motion of one object moving relative to another.
      1. Jacob didn't drive that four-wheel car that much so the tire is not...  more

      Sourav Chowhan that if there is no friction you can't walk or hold something.
      3. the last phenomenon is also an example of friction but there is something you need to know is "energy". Energy can't be destroyed but it can transform one form to another. So...  more

      Farjana Lima 1st part:
      Here, we can see three different events which we can find explanation in physics. So, let’s see:
      At first, when it comes to winter driving, the law of physics is most applicable which is Newton’s first law of motion called “ The law of...  more

      Farjana Lima 2nd part:
      Secondly, Jacob's shoes slipped and fell on the ground because the friction on the ice. This friction causes a very thin layer of water to develop on top which causes the slipperiness.
      Thirdly , when Jacob started rubbing his hands, his hands...  more

      - The law of Conservation of Energy...  more

      Taarik Hasan More surface connection produces
      more friction and grip to drive the car on snow. “Law of inertia” and sufficient
      road friction balance the force to hold the car on the...  more

      Taarik Hasan “Thermal resistivity” in his hand gloves holds the body generated heat. There’s insufficient “Thermal conductivity” to spread heat outside the gloves.

      Rubbing hands generates uneven heats due to the “Surface friction” of hand skins. There...  more

      Mesbah Abir 1. Season change in Alaska happened because of earth's annual motion. As the earth tilts around its axis and different regions of earth face the sun in different particular times, season change happens. 2. The frictional force is more when the...  more

      Zeeshan Ahmed 1. Here, I have explained a few acts of Jacob during his visit to a cold climate and his acts carried a few generalizations of physics. "His four-wheel drive car was very helpful to drive in that weather as it's tires had very good grip on the icy...  more

      Zeeshan Ahmed 2. "As soon as he started walking on the icy road, his shoes slipped and he fell on the ground." - Next here portraying Jacob's fall through an explanation of physics would be when Jacob was on an icy surface, though basically he don’t have any...  more

      Zeeshan Ahmed 3. Last but not the least, "So, he quickly started rubbing his hands together to make it warm." This act of Jacob is quite easy to understand by the ways of physics. When he rubs his hands, heat is produced due to friction. This is the force...  more

      Tanveer Tausif Ratul The 1st phenomena is the result of "friction" which opposes the vehicle's tyre rubber from sliding on slippery roads.The tread on the tires gripped the road surface while jacob was driving and from common sense,it can be realized that jacob's...  more

      Tanveer Tausif Ratul objects.When Jacob was rubbing his hand,a frictional force was produced which was emitted as heat.That energy didn't not come from the atmosphere, but rather the energy he was spending to overcome the frictional forces.

      Abrar Ibne Amin Jim All the situations described above hints at Newton’s 3rd Law & specifically Frictional force.

      1) Situation-1, Jacob’s car could travel the road despite the road was slippery. This happened as the tires had enough grooves to increase friction....  more

      Abdullah Masud In his wonderful journey, he has met some of the interesting and fundamental laws of physics. First of all, it can be noticed that surface of the ice is slippery. So in order to prevent skidding, the tire of the car had a grooved pattern moulded into the...  more

      Shafaat Shams 1. The snowy road
      is so slippery and doesn’t have enough grips. Jacob’s Car was useful there; it
      gives power to all 4 wheels at the same time. With the help of heavy car
      weight, those 4 tires made 4 friction points. The more friction it made,...  more
