Balanced force : body at rest :: Force equation :……

What is Lorentz force equation?

What kind of force keeps the body at rest?

A certain force acts on a body at rest. If after 10 seconds the body moves with a velocity of 20 m/s and if its mass is 3 kg, find the magnitude of the force acting on the body.

Right or wrong . If wrong , write the correct sentence : When a body is at rest , there is no force acting on it .

In doubling the mass and acceleration of the body, the force acting on the body with respect to the previous value

The ……. Is proportonal to the appliled force and it occurs in the direction of the force.

How should be the force applied to a body to produce shearing strees?

How should be a force applied on a body to produce shearing stress?

Fill in the blanks and complete the following paragraph . (words given: upward, friction,negligible,downward , gravitational , buoyance , very large, electric) When a body falls in air, there are three forces acting on the body : (1) the gravitational force due to the earth, acting........(2) the force of ........ due to air, acting .....(3) the force due to...... with air, acting in the direction oppositeto that of the velocity of the body. Under certain conditions, the force of buoyancy due to air and friction with air can be....... compared to the.......force of the earth. In that case (near the earth's surface) the body falls with almost uniform acceleration (g). Whenever a body moves under the influence of the force of gravity alone, it is said to be falling freely. Strictly speaking, this is true only if the body falls in vaccum.

Centrifugal force is not a real force, but it arises due to
