Weight
Summary
- Weight is the force of gravity on an object.
- Derive formula from the free fall thought experiment.
- Things that weigh a newton.
| Mass vs. Weight | |
| mass | weight |
|---|---|
| a measure of inertia (resistance to change in motion) |
the force of gravity acting on an object due to its mass |
| invariant (does not change with location) |
variable (depends upon location) |
| scalar (has magnitude only) |
vector (directed downward) |
| kg (SI base unit) |
N (SI derived unit) |
