How to use the force to push a vehicle uphill calculator
Find the steady force needed to move a vehicle up a slope against gravity and rolling resistance. Enter vehicle mass, slope angle, rolling resistance coefficient in the fields above; the force to hold speed on slope, force in kilonewtons are computed instantly and plotted on the chart so you can see how the answer changes.
Common searches this calculator answers include “pushing car uphill”, “force on a slope”, “towing uphill”, “calculate force to push a vehicle uphill”, “find force to hold speed on slope”.
Formula
Variables
- m — Vehicle mass (kg)
- th — Slope angle (°)
- crr — Rolling resistance coefficient
Worked example
With vehicle mass = 1200 kg, slope angle = 5 °, rolling resistance coefficient = 0.015, the calculator gives force to hold speed on slope ≈ 1,201.495 N; force in kilonewtons ≈ 1.201495 kN.
Frequently asked questions
What is the force to push a vehicle uphill calculator used for?
Find the steady force needed to move a vehicle up a slope against gravity and rolling resistance. It helps with questions such as “pushing car uphill”, “force on a slope”, “towing uphill”.
What is the formula for the force to push a vehicle uphill calculation?
Force to hold speed on slope (N) = m × GRAV × (sin(th)+crr × cos(th)). Force in kilonewtons (kN) = [Force to hold speed on slope] / 1000. Here m is vehicle mass (kg), th is slope angle (°), crr is rolling resistance coefficient.
What inputs do I need for the force to push a vehicle uphill calculator?
You need vehicle mass in kg, slope angle in °, rolling resistance coefficient. Each field is pre-filled with a typical example so you can see how the result responds as you edit the numbers.
How do I use the force to push a vehicle uphill calculator?
Type values into the input fields. Results and the chart update instantly. Use Reset to restore the example values, Copy results to paste them elsewhere, or Share to copy a link that preserves your inputs.
Is the force to push a vehicle uphill result exact?
Calculations use standard formulas and double-precision arithmetic, then display about seven significant figures. Real-world measurements carry uncertainty, so treat results as estimates unless your inputs are exact.
