The formula that contains an error is:
Fnet = Δv/Δt
This expression does not correctly represent net force. The correct formulas that relate net force (F_net) to other physical quantities are:
- Fnet = ma (Newton's Second Law)
- Fnet = Δp/Δt (where p is momentum, and Δp is the change in momentum over time Δt)
The term Δv/Δt represents acceleration (a), not net force (F_net). Therefore, it should not be used to define net force directly.
