At the end of this lesson, you will be able to:
understand what 1 Newton is
1 Coulomb is 6.242×1018 elementary charge carried by protons (or 1.036×10−5 mol, where 1 mol is 6.02214076×1023 particles)
go over definition of Ampere
1 A = 1 C / 1 s
it is a rate of flow of charged particles
go over:
distance (m)
speed (m/s)
acceleration (m/s²)
acceleration due to gravity because of the earth is ≃ 9.8 m/s²
watch the video, "How Much Force is 1 Newton"
go over definition of Newton
Newton's second law of motion states that F = ma, where F is the force applied, m is the mass of the object receiving the force, and a is the acceleration of the object
the newton is therefore:
F = m ⋅ a
1 N = 1 kg ⋅ 1 m/s²
OR -> a 100 g object exerts almost 1 N
or acceleration due to gravity because of the earth is 9.8 m/s²
0.100 x 9.8 ≃ 1.0
