What is the resistive force?

In physics, resistive force is a force, or the vector sum of numerous forces, whose direction is opposite to the motion of a body, and may refer to: Friction, during sliding and/or rolling. Drag (physics), during movement through a fluid (see fluid dynamics)

How do you find the resistive force of air?

Problem 1: A plane moving with a velocity of 50 ms-1 has a force constant of 0.05. Calculate its air resistance. Problem 2: An object is travelling at a speed of 20 ms-1….Answer:

How do you calculate work done against resistive forces?

It has decreased the kinetic energy of the object. The work done by the applied force and the work done against the resistive force are not the same thing, and they are not necessarily equal : Work done by the applied force = net increase in KE of object + work done against resistive force.

What is the resistive force of water?

Water resistance is a type of force that uses friction to slow things down that are moving through water. It is often called drag. Water resistance doesn’t just apply to water, it can happen to an object moving through any type of fluid. Water resistance occurs because of the particles in the liquid.

What is resistive force examples?

Friction and fluid resistance are resistive forces when the material is stationary. For example, a boat moving through still water experiences the resistive force of water resistance. If the water is moving in the same direction as the boat is moving but at a slower speed, the force of the water resistance is reduced.

What is the formula for total force?

What is the formula for force? The force formula is defined by Newton’s second law of motion: Force exerted by an object equals mass times acceleration of that object: F = m ⨉ a. To use this formula, you need to use SI units: Newtons for force, kilograms for mass, and meters per second squared for acceleration.
