What would happen to the orbits of each of the planets if the force of gravity was suddenly “turned off”? Each would move off in a different straight line. … They would orbit each other in identical but oppositely directed ellipses that share a common focus.
Similarly one may ask, how does Earth’s gravity affect objects near Earth?
On Earth, gravity pulls all objects to Earth’s center. … Gravity acts on all masses equally, even though the effects on both masses may be different because gravity causes all objects to fall at the same constant rate of 9.8 m/s2. An object in free fall means that the only force acting on the object is gravity.
Additionally, how does gravity affect the orbital motion of an object?
If the gravitational force pulling on a planet is bigger, in addition to the planet’s tendency to continue moving forward, then its orbital velocity will be bigger too. Without the Sun’s gravity, all objects in the solar system would move a straight line into outer space.
How does gravity apply to planetary motion?
Any moving object in space will travel in a straight line at the same speed forever, planets included. The planets would be moving in straight lines, but the sun’s gravity pulls them toward it. The force of gravity causes the moving planets to travel in roughly circular orbits around the sun.
How would throwing a ball on the moon be different than throwing a ball on Earth?
If a ball is thrown on the Moon, the projectile would have a greater range than if it were to have been thrown on Earth. Why is this the case? The Moon has a lower gravitaional field strength than the Earth, and it does not have an atmosphere.
What are the 3 laws of planetary motion?
There are actually three, Kepler’s laws that is, of planetary motion: 1) every planet’s orbit is an ellipse with the Sun at a focus; 2) a line joining the Sun and a planet sweeps out equal areas in equal times; and 3) the square of a planet’s orbital period is proportional to the cube of the semi-major axis of its …
What does Kepler’s third law imply about planetary motion?
Kepler’s Third Law implies that the period for a planet to orbit the Sun increases rapidly with the radius of its orbit. Thus we find that Mercury, the innermost planet, takes only 88 days to orbit the Sun. The earth takes 365 days, while Saturn requires 10,759 days to do the same.
What happens when you throw a baseball on the moon?
There is almost no atmosphere on the Moon. This means that there is no drag force to reduce the horizontal speed of a baseball pitched there. So a 90 mph fastball will still be moving 90 mph when it crosses home plate on the Moon. … A pitcher on the moon would then have a significantly harder time fooling a batter.
What would happen to a ball thrown on the moon?
There is no air resistance on the moon to slow the ball’s travel. … One can make a golf ball travel for a couple miles on the moon, but the ball would always end up landing back on its surface.
What would happen to Earth’s motion if the sun’s gravity was magically turned off?
If the Sun miraculously disappeared, the Earth (and all the other objects in the Solar System) would continue their forward motion in a straight line off into space, instead of following their almost-circular orbits. For the Earth this means it would head off towards the stars at about 30km/s (67,000mph).
What would happen to the Earth and other planets in the solar system without the sun’s gravitational force?
If it were not, a planet would move in a straight line out into space forever. The sun’s gravity pulls the planet toward the sun, which changes the straight line of direction into a curve.
Which law explain the periodic motion of planets?
Kepler’s laws of planetary motion, in astronomy and classical physics, laws describing the motions of the planets in the solar system.
Why would a baseball thrown from the surface of the Moon go higher than one thrown with the same velocity from Earth’s surface?
why would a baseball thrown from the surface of the Moon go higher than one thrown with the same velocity from Earth’s surface? The moon has less gravity than the earth and so the negative acceleration is weaker. Gravity and acceleration cause the baseball to travel upwards and then fall back down to earth.
