Net Force from Change in Velocity and Displacement

The Net Force calculator computes the net force based on the mass of an object, its change in velocity and the distance related to the change in velocity.

INSTRUCTIONS: Choose units and enter the following:

• (m) This is the mass of the object
• (s) This is the displacement
• (v2) This is the end velocity
• (v1) This s the initial velocity

Net Force (F): The calculator returns the net force in newtons.  However, this can be automatically converted to compatible units via the pull-down menu.

The Math Science

The formula for the Net Force based on change in velocity over a distance is:

     `F = m * (v2^2 - v1^2)/(2*s)`

where:

• F is the Net Force
• m is the mass of the object
• s is the total displacement
• v2 is the initial velocity
• v1 is the final velocity
