We might say that an unbalanced force causes a ball to start moving. If a ball is resting on a surface, gravity is pulling down and the surface is pushing up against it. Things (forces) are in balance and the ball is still. Drop the surface out from under the ball and that ball begins to fall as gravity has no opposing force to balance it.
Any lateral force on the ball that can overcome its rolling resistance will cause the ball to move. The inertia of the ball is such that it "wants" to remain at rest. Some unbalanced force will have to act on the ball to cause it to start moving. A ball on a pool table sits still until struck by a cue or another ball. It takes an "outside" force to "unbalance" the forces acting on a ball that is at rest to cause it to move.
The ball keeps moving forward because of its momentum, which is not a force.
Because you never see objects moving forever. If you roll a ball across a table then a force causes it slow down and stop called friction.
Inthe kicking force, kinetic energy is acting on the ball together with Gravitational Potential Energy. Whereas the part where aother force is acting on iit while the ball is not moving is alsoocontrolled by gravitaitional potential energy.
The opposite direction. To stop a moving object requires an acceleration in the direction opposite its motion.
Newton's first law states that every object that is moving will continue moving at constant speed in a straight line until an unbalanced force acts upon it. An object at rest will remain at rest until an unbalanced force acts upon it. A golf ball remains at rest until the unbalanced force of a golf club. Then, it will continue moving at constant speed until an unbaleced force acts on it. What slows it down is friction. Then, the hole or wall will stop it.
No. The force keeping a ball on a string moving in a circle is centripetal force, i.e. force pulling the ball to the center of the circle.
Gravity
to reduce the impact, and make it hurt less.It has to do with the retarding force that would be exerted by the ball on the hand if the hand were to just stop it - the force would be high since the ball's motion is stopped immediately. But by moving the hand in the direction of the motion of the ball, it allows the velocity of the ball to decrease in a longer interval of time (and so, causes the retarding force to decrease). This means that the force exerted by ball on the hand is much lower, and the fielder does not get hurt.
The ball keeps moving forward because of its momentum, which is not a force.
The action force is your hand moving back. The reaction force is the ball moving the other way.
perpendicular to the ball's path
Because you never see objects moving forever. If you roll a ball across a table then a force causes it slow down and stop called friction.

An object that is slowing down is moving or in motion until it stops.It is not necessarily accelerating, as an accelerating object will begin traveling in the opposite direction after it stops. For example, a ball thrown into the air will slow down as the force of the earth's gravity causes it to accelerate downwards. For an instant, the ball will be motionless before moving towards the earth.
The roulette ball stays in motion due to centrefugal force. Since the ball is moving fast it "wants" to just go straight (Newton's 1st law) but the contact force of the metal track exerts an inward force that keeps it moving in a circle. Eventually, as the ball loses momentum, the force of gravity will be greater and the ball will then fall into a pocket.

The force that causes the ball to fall to the ground is gravity. Gravity is a natural force that attracts objects towards each other, and in the case of the ball falling, it is being pulled towards the Earth's center by the force of gravity.
