So, here’s a guy, who literally is moving an object. He’s applying a force of 700 Newtons, which is force and he’s moving it two meters. So, you would say 700 times 2, you get 1400 joules, okay? Work is measured in energy. So, how much energy was expended? So, if you ...
If the unit of length is meters and the magnitude of the force is measured in newtons, then the work done is \(36\) J.反馈 收藏
Weight is commonly measured in Newtons. Mass and weight example - the moon In the below example, we've featured an astronaut on earth and on the moon. The Moon's gravity is much less than the Earth's gravity - approximately one sixth. So, a 100 kg astronaut weighs 980N on Earth. On...
(n/m 2 or kg m -1 s -2 ). interestingly, this name was given in 1971. before that pressure in si was measured in newtons per square metre. pascal formula: what is the cgs unit of pressure? the cgs unit of pressure is barye (ba), equal to 1 dyne·cm −2 , or 0.1 pa. ...
