True or false Because of earths gravitational pull and their own inertia projectiles travel in a straight path?

False
Because gravity is constantly pulling on the projectile while the projectile is trying to move forward in a straight line, the projectile will move in a CURVED path and fall down to earth.

Explain why when you throw a ball it travels in an arc and not in a perfectly straight line?
This is called projectile, because of Earths gravitational pull and their own inertia ,projetile follows a curved path. They have both horizontal and verticals velocities.
Why do planets orbit around the sun?
Since the Sun has the most mass of all the objects in the solar system, it has the strongest gravitational pull. If there were another object in the solar system with more mass than the Sun, the planets (and the Sun itself) would orbit it. If there were no Sun's gravity (or other gravitational forces) the planets would travel in straight lines instead of orbits.
How inertia and gravity combine to keep earth in orbit?
gravity and inertia combine to keep earth in orbit because the suns gravity keeps the earth in orbit and the inertia keeps the earth from going in a straight line.
What holds bodies in their positions in the solar system?
A combination of the bodies' inertia, and the Sun's gravitational attraction.
Why does planets appear to move around in the sky because?
it moves around the sun because gravity pulls it tward the sun, and inertia moves in a straight line, working together, gravity make inertia orbit (move) around the galaxy!
Why is earth not thrown off of its orbit?
Because the sun's gravitational pull and inertia hold it.

How does gravity work against inertia?
The moon has inertia and wants to keep going in a straight line but the earth has a larger gravitational pull and wants to pull the moon towards it. This causes the moon to circle or orbit the earth.
What do the forces of inertia and gravitational pull of the moon cause?
Tides
What are two effects that forces have on motion?
inertia and gravitational pull
What force causes the planets to stay in orbit around the sun?
The sun's gravitational force pulls its satellites towards it, while each satellite has its own inertia going in a straight line perpendicular to the gravitational force. With both forces working together, the satellite goes in a diagonal direction that is always changing with the change of its direction of inertia, causing the revolution.
Gravitational force works in straight and direct direction but rotating of the planets around the Sun are in circular paths How could the gravitation force impact in this way?
The revolution (not rotation) of the planets around the sun is not an example of straight gravity. It is a combination of two forces: gravity and inertia. Gravity, working without inertia, would pull the planets into the sun, in a straight line. Inertia, working without gravity, would send the planets sailing through the galaxy, in a straight line. The total effect of these two opposing forces is an orbital path. Gravity and inertia, in this situation, are also referred to as centripetal and centrifugal forces.
What tries to make planet move in a straight line?
Its inertia.
Why earth revolves round the the sun?
the earth revolves around the sun because of two main components in space. Inertia and gravitational pull. The sun has a gravitational pull on all of the planets but to keep them from colliding with the sun inertia gives them the motion to keep revolving and not getting closer to the sun.
Why do planets orbit around the sun?
Since the Sun has the most mass of all the objects in the solar system, it has the strongest gravitational pull. If there were another object in the solar system with more mass than the Sun, the planets (and the Sun itself) would orbit it. If there were no Sun's gravity (or other gravitational forces) the planets would travel in straight lines instead of orbits.
What is earths gravitational force compared to mars?
Earths gravitational force compared to mars is greater than mars. That means that objects are easily pulled into earth, whereas it is harder to pull objects into mars, because the gravitational pull is less than earth. With that, satellites on earth could easily fly out of orbit while they are orbiting mars because they have more inertia. With that, the gravitational pull isn't strong enough to overcome the inertia.
What keeps the planets and the sun in place?
Gravity, inertia, and gravitational force.
