Question:
It has been suggested that spacecraft could be propelled by the radiation pressure from the sun. What must be the surface mass density (kg/m2) of a perfectly reflecting sheet so that at a distance of one astronomical unit the force due to radiation pressure is twice that due to the gravitational attraction between the reflecting sheet and the sun? How will the ratio of radiation force to gravitational force change as the reflecting sheet accelerates away from the sun?
Step by Step Answer:
Because the sheet is perfectly reflecting the force on it due ...View the full answer

In Physics, a force is an influence that can change the motion of an object. A force can cause an object with mass to change its velocity, i.e., to accelerate. Force can also be described intuitively as a push or a pull. A force has both magnitude and direction, making it a vector quantity. In this video, the concept of force and torque is demonstrated with the practical application of changing the flat tire of the car.
