Balanced and Unbalanced Forces

In a tug-of-water between the teams A and B, the rope breaks at a point which is nearer to A. Then

Which side will the block move and why?

Using a horizontal force of $200$ Newton we intend to move a wooden cabinet across of floor at a constant velocity what is the friction force that will be exerted the cabinet.

Is Inertia a balanced force?

What is the force applied is mass is $8 \mathrm{kg}$ and acceleration is $40 \mathrm{m}/{\mathrm{s}}^2$?

Give two examples under the condition that sum of all linear forces acting on the body should be equal to zero.

Assertion: If the resultant force acting on a body is zero, then body is in equilibrium.

Reason: Resultant force on a body is equal to algebraic sum of all forces acting on the body.

When balanced forces act on a body, the body :

A train pulls some carriages. The train exerts a force of $40000 \mathrm{N}$ and frictional forces act in the opposite direction with a force of $35000 \mathrm{N}$. The total mass of the train and carriages is $200000 \mathrm{kg}$. What is the acceleration of the train?

When an unbalanced force acts on a vehicle, which of these quantities changes?

A motorbike accelerates with a force of $1500 \mathrm{N}$. It experiences air resistance, which acts in the opposite direction with a magnitude of $1200 \mathrm{N}$. Calculate the unbalanced force that acts on the motorbike.

Following question contain four steps. Fill in the blank on right side according to left side step.

Pressure : Pascal :: Force : _____

Attraction force applied by earth on all the bodies. (gravitational force/electromagnetic force)

Force has magnitude but no direction.

Derive the unit of force using second law of motion. A force of $5$ $\mathrm{N}$ produces an acceleration of $8 \mathrm{m}/{\mathrm{s}}^2$ on mass $m_1$ and $6 \mathrm{m} {\mathrm{s}}^{-1}$ on mass $m_2$. What acceleration would same force provide if both masses are tied together?

Give reason for the shapes of superfast trains is streamlined.

Distinguish between balanced force and unbalanced force. Give examples also.

What type of changes are brought by force on a body? Give two examples.

Why does a bicycle slow down if we stop pedalling?

How is force related to acceleration produced in a body?
