Newton's Second Law of Motion
Текст на Статията
- Coming back to...
- Newton's Second Law of Motion!
- So, what did you want me to explain again?
- Ok... for Newton's Second Law of Motion:
- It's Newton's second Law of motion!
- 'The Force of a certain object equals its Mass times its Acceleration. (Force = Mass x Acceleration)'
- I wish I had enough force to lift it!
- Here, I'm holding a tennis ball. The tennis ball has very little mass, so I don't need lots of force to lift it.
- Over here, I'm holding a bowling ball. The bowling ball has lots of mass, so I don't need much more force to lift it.
- Squeeeak! Help!
- Grunt!
- Good job you got it!
- Can you explain it to me then?
- Ohhh I get it!
- Here goes! So, if and object has more mass, it will be harder to lift than an object with less mass, because you need more force to lift more mass!
- Now I just need you to explain Newton's third law...
