If A ball is moving in a circular horizontal path the net force on the ball is in which direction?
The net force on the ball is directed towards the center of the circle, providing the centripetal force required to keep the ball moving in a circular path. This force is perpendicular to the velocity of the ball at any given moment.
Why when a ball thrown vertically upwards by a man in a moving train comes back to his hand?
that depends on 3 factors, how big is the circle, how fast is the train, and how high is the ball thrown also it is to be considered that u are assuming the natural (actual) conditions like the air thrust is present or hypothetical conditions that there is no air thrust. Under all ideal conditions i.e. no air thrust etc. the ball will move tangentially to the path of the circle the train is traversing.
How will the path of the ball appear to you if you accidentally drop a ball while inside a moving bus?
If the bus is moving at a constant horizontal velocity relative to you and the ball, there is no horizontal acceleration and therefore no horizontal force. The only force acting on the ball is gravity, which is vertical, so the ball will just fall straight down next to you.
Is a moving body an example of an object which moves along a straight path?
Yes, a moving body is an example of an object that moves along a straight path if its motion is in a single direction without deviating from that path. For instance, a car moving in a straight line on a road or a ball rolling in a straight line on a flat surface are examples of motion along a straight path.
What force causes a ball to accelerate around a pole?
The centripetal force is what causes a ball to accelerate around a pole. It is directed towards the center of the circular path and keeps the ball moving in a curved trajectory.

What will happen if you throw a ball upwards in a moving bus?
Relative to the person in the bus, the ball goes in a vertical line. To a person outside the moving bus it would go in a parabolic path.

If the bus is moving at a constant horizontal velocity relative to you and the ball, there is no horizontal acceleration and therefore no horizontal force. The only force acting on the ball is gravity, which is vertical, so the ball will just fall straight down next to you.
If the 7 train transfer to the PATH train?
Yes. It is correct to say that the 7 train transfer to the PATH train.
Does the 7 train transfer to the PATH train?
Yes. It is true to say that the 7 train transfers to the PATH train.

The centripetal force is what causes a ball to accelerate around a pole. It is directed towards the center of the circular path and keeps the ball moving in a curved trajectory.
Why does a ball that is thrown horizontally stayin the same path?
A ball that is thrown horizontally will stay in the same path because there are no horizontal forces acting on it to change its motion. In the absence of air resistance and other external forces, the ball will continue moving at a constant horizontal speed due to its inertia.
What would happen to an object if the centripetal force acting on it stops?
Picture a ball on a string being whirled about the head of an experimenter. If the string breaks, the centripetal force disappears. The ball leaves on a tangent path form its (previous) circular path. Yes, it's that simple. The string provided centripetal force, by virtue of its tensile strength, to the ball to keep that ball moving in a circle. When the string broke, there was no force left to accelerate the ball "in" and keep it moving in an arc.
Explain how an observer uses a frame of reference to detect motion?
This is what we call relativity. As we being on the platform observe one sitting in a train at rest throwing a ball vertically upward and catch it back as it comes downward, we see the ball is going along a straight line. Now the same phenomenon is observed by us when the train is at uniform speed. We still stand on the platform which is at rest. But the man in the train is moving at uniform speed. Now for him he experiences the same straight line movement of the ball up and down. But for us being on the platform the ball seems going along a parabolic path. This is what we call relativity. Our frame of reference is the platform at rest. But the man in the train has his frame of reference moving at uniform speed.
What is the magnitude of the tension in the string when the ball is at the bottom of the circle?
The magnitude of the tension in the string at the bottom of the circle is equal to the sum of the gravitational force acting on the ball and the centripetal force required to keep the ball moving in a circular path.
