As a water drop builds up and out, usually bulging over the sides of the penny, the cohesive forces will eventually be overcome by the force of gravity on the water molecules. As drops of water are added onto a penny, the adhesive force between the water and the penny keeps the water from falling off.Ĭohesive forces are strong, but not unbreakable. The attraction of water molecules to other substances, like soil or glass, is called adhesion. Surface tension is strong enough to support insects that crawl across the water's surface, like water striders (Gerridae). The cohesive force that occurs between water molecules is so strong that, at the water's surface, it creates a "skin", which is known as surface tension. The attraction between water molecules is called cohesion. There are two types of "stickiness" in this demonstration: cohesion and adhesion. The polarity of the water molecule can also cause it to be attracted to molecules of other polar substances. This weak link is called a hydrogen bond. A weak link occurs between the negatively charged oxygen atom of one water molecule and the positively charged hydrogen atoms of a neighbouring water molecule. The two hydrogen atoms are slightly positive, and the oxygen atom is slightly negative. We will have to wait and see.In this demonstration, students' assumptions are challenged as they observe the power of surface tension in water droplets.Īlthough a water molecule has an overall neutral charge, the actual structure of a water molecule makes it a polar molecule (it has a positive end and a negative end). I am not saying it will, but I wouldn’t be completely shocked if Cybertruck ends up catching up to the Lightning in terms of total production by 2025. If there’s something Tesla has been incredible at over the last few years is ramping electric vehicles to mass production. You can never count Tesla out in my opinion.įord has accelerated its planned production for the Lightning to a rate of 150,000 units to be achieved around mid-2023 when Tesla also plans to be in volume production with the Cybertruck, according to Musk’s most recent comments. However, he might come to regret his words. While Tesla still dominates the EV market, especially in the US, Ford certainly has the lead when it comes to electric pickup trucks. However, the vehicle program was delayed several times, and now Tesla plans to bring the Cybertruck to market in 2023. Tesla first unveiled the Cybertruck in 2019 and claimed that it would go into production in 2020, which would have made Tesla the first to market with an electric pickup truck. Rivian was actually first to market with the R1T electric pickup, but even though Ford started producing about six months later, the automaker was quickly able to catch up to the startup by using its mighty manufacturing capability.Īs for Tesla, Musk might have his own Cybertruck, but it’s a prototype and one of only a few. Ford has quickly built a lead in electric pickup trucks with the F-150 Lightning. The comment even prompted a response from Musk on Twitter who said, “Thanks, but I already have one” – seemingly referring to the Tesla Cybertruck.įarley is not wrong. We’re really on a mission at Ford to lead an electric and digital revolution for many, not few, And I have to say the shining light for us at Ford is this beautiful Lightning made right down the road in Dearborn, right here in the state of Michigan, already the leader of all EV pickup trucks in our industry in the United States. Last year, Ford’s CEO praised Tesla in an internal meeting where he said “no one does electric better.”īut now he actually has an area where Ford does electric better, and that’s electric pickup trucks.įarley commented during a press event to announce Ford and DTE Energy’s deal for the largest renewable energy purchase in US history: It actually happens somewhat frequently with Tesla since the automaker has built such an incredible lead when it comes to electric vehicles that it is hard not to acknowledge it.įord CEO Jim Farley has had great things to say about Tesla in the past. Of course, it still happens every now and again. In the auto industry, or any competitive industry really, it is rare that CEOs will directly call each other out or even mention the other company in order to avoid highlighting the competition. Do we have a little friendly competition in the electric pickup market? Ford CEO Jim Farley has called out Tesla CEO Elon Musk over the Dearborn, Michigan-based automaker’s lead in electric pickup trucks.
