Want this question answered?
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.
The curved path is the result of gravity and inertia acting on the ball. As it leaves the table gravity pulls it to the ground at an increasing rate while inertia keeps it moving in its original direction. The table prevents the rolling ball from falling thus negating that curvature caused by gravity, and making it follow a straight line.
YES
YES , it can be possible because according to law of inertia if an object is moving andexternal force on it is zero then it keeps moving with constant velocity (constant speedin a straight line).Keep that up for a while and the object accomplishes some serious displacement.
No. There is no outward force exerted in circular motion. Inertia is the reasoning. For example, if your in a car going around a roundabout than you are going one way but the car is going the other hence Inertia is present.
The force of gravity keeps the space station in orbit as well as inertia that keeps the space station moving in a straight line.

gravity
Inertia.
A moving object keeps moving, unless you force it to stop. It keeps moving in a straight line, unless you force it to change direction. It keeps moving at a constant speed, unless you force it to speed up or slow down. A stationary object remains stationary, unless you force it to start moving.
inertia. because inertia keeps things going in a straight line, and that kind of throws it forward, but the direction of "foward" keeps changing as the car or roller coaster turns.
