 # Does Force Equal Velocity?

## How do you find velocity with net force?

Net force = force minus body weight.

Acceleration = net force ÷ body mass (body weight ÷ the acceleration of gravity [9.81 m/s/s]) Velocity = acceleration × time..

## Is force directly proportional to velocity?

The net force is proportional to the rate of change of velocity, which we call acceleration.

## Why is velocity not a force?

Velocity does not act on an object. A force pushes or pulls on an object, but velocity is simply something an object has.

## What is the relationship between power force and velocity?

In the straightforward cases where a constant force moves an object at constant velocity, the power is just P = Fv. In a more general case where the velocity is not in the same direction as the force, then the scalar product of force and velocity must be used.

## Does velocity affect power?

Power–Velocity Relationship Power output, when plotted as a function of muscle shortening velocity (Figure 18(a)), shows that power output first increases at low velocities, attains a peak at intermediate velocities, and then gradually declines to a value of zero at Vmax.

## What is the relation between speed and force?

Speed is the distance travelled in a set amount of time. More force will give an object greater speed. Greater mass requires more force to move.

## How do you convert velocity to force?

If you do not want to use acceleration but only the velocity of the body there is a formula to get the unit of newtons. This formula is stated as force = power / velocity. Their SI units are newtons for force, watts for power and m/s for velocity. Remember that the unit newton is equal to kg * m/s^2.

## What is Newton formula?

Force (Newton) = Mass of body × Acceleration. Or, F = [M1 L0 T0] × [M0 L1 T-2] = M1 L1 T-2. Therefore, Newton is dimensionally represented as M1 L1 T-2.

## What are the 4 properties of force?

Fundamental force, also called fundamental interaction, in physics, any of the four basic forces—gravitational, electromagnetic, strong, and weak—that govern how objects or particles interact and how certain particles decay.

## What is force * velocity?

The force-velocity curve is simply a relationship between force and velocity and can, therefore, be displayed on an x-y graph (Figure 1). The x-axis (i.e. horizontal axis) indicates velocity, for example, this may represent muscle contraction velocity, or velocity of movement (measured in meters per second).

## Does force equal mass times velocity?

The second law explains how the velocity will change. The law defines a force to be equal to change in momentum (mass times velocity) per change in time. … For an object with a constant mass, the second law can be more easily expressed as the product of an object’s mass and it’s acceleration (F = ma).

## Does velocity increase with mass?

2 Answers. Mass doesn’t affect speed directly. It determines how quickly an object can change speed (accelerate) under the action of a given force. Lighter objects need less time to change speed by a given amount under a given force.

## What is the difference between speed and velocity?

The reason is simple. Speed is the time rate at which an object is moving along a path, while velocity is the rate and direction of an object’s movement. Put another way, speed is a scalar value, while velocity is a vector.

## Does velocity increase with force?

It would be better to say a greater force causes a greater CHANGE in velocity for an object. … In that particular case, a greater gravitational force means that the planet must have a circular orbit with a greater speed.

## What is force equal to?

According to NASA, this law states, “Force is equal to the change in momentum per change in time. For a constant mass, force equals mass times acceleration.” This is written in mathematical form as F = ma. F is force, m is mass and a is acceleration.
