The earth revolves around the sun in its orbit as shown in the figure. Is there any difference in the amount of gravitational force of the sun towards the earth when the earth moves from a point A to point B on its orbit? Explain.​

Find v(t), given acceleration a(t)=7j and initial velocity v(0)=k

If the force applied to an object remains constant, is more power needed for the object to move faster ? explain

When a bicycle coasts uphill, it moves slower and slower as it climbs. why? a. its kinetic energy is transforming into heat energy. b. its potential energy is transforming into kinetic energy. c. its kinetic energy is transforming into potential energy and heat energy. d. its potential energy is transforming into kinetic energy and heat energy.
