Which of the following best describes why projectiles move in a curved path?

Which of the following best describes why projectiles move in a curved path? They have horizontal velocity and vertical acceleration. The acceleration of an object is in the same direction of which of the following?

Why is the path of its motion curved?

Obviously, curved motion is motion along a path that is not straight. Therefore, an object following any type of curved motion will necessarily be changing its direction as it moves. So, if an object travels in a curved path, it changes velocity, and, thus, accelerates. This acceleration must be tied to a force.

Which explains why astronauts seem weightless in orbit?

Earth-orbiting astronauts are weightless for the same reasons that riders of a free-falling amusement park ride or a free-falling elevator are weightless. They are weightless because there is no external contact force pushing or pulling upon their body. The force of gravity is the only force acting upon their body.

What exerts the strongest gravitational force on Earth?

One of Sir Isaac Newton’s accomplishments established that the gravitational force between two bodies is proportional to their masses. All other things being equal, the planet with the strongest pull is the one with the largest mass, which is Jupiter.

Is gravity pulling or pushing?

4 Answers. In general relativity, gravity neither pushes nor pulls. So in General relativity, gravity is not seen as being a force, instead it is the result objects travelling in the most direct way in a region of curved spacetime.

Can time be bent by gravity?

Also, under Einstein’s theory of general relativity, gravity can bend time. When anything that has mass sits on that piece of fabric, it causes a dimple or a bending of space-time. The bending of space-time causes objects to move on a curved path and that curvature of space is what we know as gravity.
