Answer the following questions :
In ithe following figure, an orbit of a planet around the sun (s) has been shown. AB and CD are the distances covered by the planet in equal time. Lines AS and CS sweep equal areas in equal intervals of time. Hence , areas ASB and CSD are equal.

Write the law regarding area swept.

Answer the following questions : Observe the given figure showing the orbit of a planet moving around the sun and write the three laws related to it.

The straight line joining the planet and the sun sweeps equal____in equal interval of time

The orbit of a planet is an ellipse, line joining the planet and the sun sweeps equal areas in equal intervals of time F=(Gm_1m_2)/(r^2) , T^2 prop R^3

A body moves in a circle covers equal distance in equal intervals to time. Which of the following remains constant?

Fill in the blanks with appropriate words and write the completed sentences: According to Kepler's second law,the line joining the planet and the Sun....... in equal intervals of time.

Answer the following questions: The following table shows the distances covered by a bus in equal time intervals. Draw a graph of distance against time taking the time along the X-axis and distance along Y-axis. Does the graph show a direct proportionality between distance and time?

Answer the following questions: A train is moving with a uniform velocity of 60km/hout for 5 hours. The velocity-time graph for this uniform motion show in figure. Is there a relation between the distance covered by the train between 2 and 4 hours and the area of a particular quadrangle in the graph? What is the acceleration of the train?

Answer the following questions: The changes in the velocity of a car in specific time intervals are given in the following table.The velocty-time graph in figure shows that, The velocity changes by equal amounts in equal time intervals. Thus, this is uniformly accelerated motion. How much does the velocity change in every 5 seconds? Find the distance covered by the car in the time interval 10 seconds to 20 seconds.

A particle covers equal distance aroung a circular path, in equal intervals of time. Which of the following quntities connected with the motion of the particle remains constant with time?

Answer the following questions : Anu and anand have concave and convex lenses respectively . They took lenses in sunlight and tried to burn two pieces of paper of equal areas and temperature . State which lens will burn the paper. Give the reason . Explain with the help of diagram, why the other paper did not burn.
