Rishi's Dad: Sorry Rishi. I didn't mean to slam the brakes.
During the incident, Rishi was wondering how he got hurt so bad even though he was wearing his seatbelt.
Rishi let me tell you about Newton's three laws of motion. The first law states that and object in motion will stay in motion and an object at rest will stay at rest . What you just experienced is when we were driving and I slammed the breaks, you were in motion. The seatbelt held you back from going through the windshield. You could have got even more hurt if you didn't wear your seat belt.
The next day...
Wow, that airplane is going so fast! I can only imagine how much force it would take to push that giant airplane forward.
Rishi's dad enters
Even though planes travel very fast in the air, it takes a long time to accelerate on the tarmac in order to takeoff. Newtons second law of motion states that the acceleration of an object increases with with increased force and decreases with increased mass. The way to find the force of any object is F= A times M where F equals force, A equals acceleration, and M equals mass. This means that an object with a heavy mass does not accelerate fast unless the object has a major power source.
The next week...
Hopefully we can learn some science as well!
Wow, I cannot wait for this rocket liftoff!
30 minutes later..
Wow, the third law of motion. For every action there is an equal and opposite reaction. When the rocket was at rest the forces were balanced so it was just sitting still. When the rocket lift off the force of fire and heat shoots out of the rocket and the rocket propels upward.
