Force is measured in newtons (N) with 1 N being the force required to impart an acceleration of:
1 m/s to a mass of 1 kg |
|
1 m/s2 to a mass of 1 kg |
|
1 m/s2 to a mass of 1 kg/s2 |
|
1 mph to a mass of 1 kg |
Weight is a force that describes the attraction of gravity on an object. Force is measured in newtons (N) with 1 N being the force required to impart an acceleration of 1 m/s2 to a mass of 1 kg.

The rows of the Periodic Table of the Elements are called:
shells |
|
groups |
|
periods |
|
families |
The rows of the Periodic Table are called periods and contain elements that have the same number of electron shells ordered from lower to higher atomic number.
Elements that belong to the same period in the Periodic Table of the Elements have the same number of:
atomic mass units |
|
electrons |
|
electron shells |
|
protons |
The rows of the Periodic Table are called periods and contain elements that have the same number of electron shells ordered from lower to higher atomic number.
Which of the following is the formula for power?
\(P = {w \over t}\) |
|
\(P = \vec{w}t\) |
|
\(P = {\vec{w} \over t}\) |
|
\(P = w t\) |
Power is the rate at which work is performed or work per unit time: \(P = {w \over t}\) and is measured in watts (W).
