Planet Impact: Home
by knannIn this interactive online activity, students investigate how the gravitational force of a large solar system body, such as Jupiter, can affect the path of a smaller body, such as a comet. They will launch a comet to learn how gravity can change its path. They also learn how changing the speed, the angle of approach, or the masses of large and small bodies affects the force of gravity on a comet. Students are challenged to use this knowledge to crash their own comet into Jupiter or make their comet fly past the planet without colliding with it
