Diy Canoe Building Plans Meaning

Who discovered that force is the cause of motion? Answer Galileo Galilei. Who formulated the universal law of gravitation? Sir Issac Newton.

Which force causes ch 10 maths class 10 example 2 year things to fall towards the earth? Gravitational force. Who found out the value of gravitational constant G?

Henry Cavendish. What is the unit of gravitational constant G? Give reason-stone falls towards the earth but earth do not rise towards the stone. Stone falls due to gravitational force exerted by the earth. Earth do not move towards the stone as the mass of earth is much more than that of the stone. Account for the following: i On moon, man feels lighter than earth. Justify your answer. On earth value of g is maximum at poles and minimum at the equator.

At poles radius of earth is less so value of g is more, at equator radius of earth is more Ch 5 Maths Class 10 Ex 5.2 Year so value of g is. State any four natural phenomena explained by universal law of Gravitation.

Explain what happens to the force between two objects if: i The mass of one object is doubled? Value is maximum at poles and minimum at equator of the earth.

Explain : i Universal gravitational constant ii Free fall Answer. The numerical value of G is equal to 6. The value of G was found out by Henry Covendish by using a sensitive balance. While falling there is no change in the direction of motion of the objects.

State the universal law of gravitation. Mention four phenomena which can be explained by this law. Ch 10 maths class 10 example 2 year Answer: Universal law of gravitation states that the force of attraction between two objects is proportional to the product of their masses and inversely proportional to the square of the distance between. Four phenomena which can be explained by this law are: i The force that binds us to earth.

In which direction do the following forces act when an object is in motion? Explain with the help of an example. Will his weight remain the same when measured at the equator? Will there be an increase or decrease is his weight?

No, his weight will not remain same as that at the poles. There will be a decrease in his weight at the equator. Also, the force of gravity decreases from poles to the equator. Give reasons: i A piece of paper takes much longer to fall than a ch 10 maths class 10 example 2 year through the same distance, when both are dropped simultaneously from roof. In which direction do the following forces act when an object is in motion: i Frictional force ii Gravitational force iii Centripetal force Answer.

Mass remains the same when weighed at equator but weight decreases. Write any three differences. Since, on equator, gravitational force is less, so the Class 10 Maths Ch 2 Pdf Examples ch 10 maths class 10 example 2 year of the bar of metal decreases.

Write three points of differences between mass and weight. How much would a 70 kg astronaut weigh on moon? What would be his mass on the earth and on the moon? Differences between mass and weight: Mass. Previous Post Next Post. Contact form. LinkList ul li ul'. Tabify by Templateify v1.
