# Can a body in free fall be in equilibrium?

## Can a body in free fall be in equilibrium?

Yes! Such an equilibrium situation is called dynamic equilibrium . A body is said to be in equilibrium if the net force acting on the body is zero. The two forces acting on the book, gravitational force & normal force, are equal and opposite giving a zero net force.

Can an object be in equilibrium if only one force acts on it?

If there is only one external force (or torque) acting on an object, it cannot be in equilibrium. True, as the sum of forces cannot be zero in this case unless the force itself is zero. If an object is in equilibrium there must be an even number of forces acting on it.

Can a body be in equilibrium if it is in motion?

Yes, a body can be in equilibrium if it is in motion. We know that a body is said to be in equilibrium if the net force acting on it is zero. By the second law of motion, we know that the acceleration in such bodies is zero. No acceleration implies constant velocity.

### What are the two main conditions for equilibrium?

Conditions for equilibrium require that the sum of all external forces acting on the body is zero (first condition of equilibrium), and the sum of all external torques from external forces is zero (second condition of equilibrium). These two conditions must be simultaneously satisfied in equilibrium.

What are the condition of consumer equilibrium?

The solution to the consumer’s problem, which entails decisions about how much the consumer will consume of a number of goods and services, is referred to as consumer equilibrium. This condition states that the marginal utility per dollar spent on good 1 must equal the marginal utility per dollar spent on good 2.

What is Consumer equilibrium with example?

Consumer’s equilibrium is a situation when a consumer spends his given income on the purchase of one or more commodities in such a way that he gets the maximum satisfaction and has no urge to change the level of consumption.

## What is the condition of consumer equilibrium in one commodity case?

Consumer’s Equilibrium refers to the situation when a consumer is having maximum satisfaction with limited income and has no tendency to change his way of existing expenditure. The consumer has to pay a price for each unit of the commodity. So, he cannot buy or consume unlimited quantity.

What are the conditions of consumer equilibrium under utility analysis?

According to Mashallian utility analysis, when expenditure of a consumer has been completely adjusted, that is, when marginal utility in each direction of his purchases is the same, it is called consumer’s equilibrium. Then he has no desire to buy any more of one commodity and less of another.

What are the two conditions that are met if a consumer is maximizing utility?

1. She spends all available income. 2. She equalizes the marginal utility per dollar for all goods.

### What is Consumer equilibrium with diagram?

In order to display the combination of two goods X and Y, that the consumer buys to be in equilibrium, let’s bring his indifference curves and budget line together. We know that, Indifference Map shows the consumer’s preference scale between various combinations of two goods.

What is the importance of consumer equilibrium?

Importance of Consumer Equilibrium It allows a consumer to maximise his/her utility from the consumption of one or more commodities. It helps arrange the combination of two or more products based on consumer taste and preference for maximum utility.

When a consumer consumes two goods he will be in equilibrium when?

Suppose a consumer consumes only two goods, X and Y. They will attain equilibrium only if they allocate their given income on the purchase of X and Y in such a way that per rupee, the MU of both the products are equal and the consumer gets the maximum TU.

## What is the meaning of consumer?

Defining Consumers. A consumer is a person (or group) who pays to consume the goods and/or services produced by a seller (i.e., company, organization).

What is meant by market equilibrium?

Equilibrium is the state in which market supply and demand balance each other, and as a result prices become stable. Generally, an over-supply of goods or services causes prices to go down, which results in higher demand—while an under-supply or shortage causes prices to go up resulting in less demand.

What is the example of equilibrium?

An example of equilibrium is in economics when supply and demand are equal. An example of equilibrium is when you are calm and steady. An example of equilibrium is when hot air and cold air are entering the room at the same time so that the overall temperature of the room does not change at all.

### What is the formula of equilibrium?

Law of chemical equilibrium: To determine the equilibrium constant, first consider the simple reversible reaction at constant temperature. Keq is the equilibrium constant at given temperature. Keq = [C] × [D] / [A] × [B] This equation is called equation of law of chemical equilibrium.

What is the formula for calculating equilibrium price?

To determine the equilibrium price, do the following.

1. Set quantity demanded equal to quantity supplied:
2. Add 50P to both sides of the equation. You get.
3. Add 100 to both sides of the equation. You get.
4. Divide both sides of the equation by 200. You get P equals \$2.00 per box. This is the equilibrium price.

What happens to equilibrium price and quantity when demand increases?

An increase in demand, all other things unchanged, will cause the equilibrium price to rise; quantity supplied will increase. A decrease in demand will cause the equilibrium price to fall; quantity supplied will decrease. A decrease in supply will cause the equilibrium price to rise; quantity demanded will decrease.
