Jumping Dirt bikes

Question- What does physics have to do with dirt biking?

Our Research,
What does science have to do with dirt biking. Science has so much to do with dirt biking and I am going to be telling you about it. When you are riding up to a jump you can’t let off because the kinetic friction between the tires slows you down and you will nose dive off the jump. When you come off the lip of the jump you go up in the air and there are two forces acting on you. The forces are air resistance and gravity. If there was no gravity you would keep flying up in the air but gravity helps to bring you back down. Gravity also helps you stay on your bike. When you land Newton’s third law comes into place. If you come up short on the jump and case it your momentum pushes you forward over the bars. All the forces that act on you while jumping are free fall, friction, air resistance , Newton’s third law, momentum, velocity and action reaction. Eventually his first law which is “an object in motion will stay in motion unless acted upon by an unbalanced force.” The unbalanced force would be the brakes and also friction. When you land action reaction comes into place. The reason why action reaction happens is because your shocks compress to help make you land smother than they come right back up.
There are a couple different ways to jump a dirt bike. One way to jump a dirt bike is by sitting down. When you sit down off a jump it makes you go farther. If you don’t stand up you the momentum will end up throwing you backwards. Another way to jump is how everybody always does it, standing up. When you want to go faster in the air you can whip. It makes you stay lower to the ground. When you whip it changes your velocity.
