Why do you need to use force to move a ball up a ramp when it moves downward by itself?
The force of gravity makes the ball move downward. To move it upward, you need to supply enough force to compensate for this (to stop the downward motion) plus a little extra (to cause the ball to move upward).
Is a ball an object that moves?
no,because you need your movement to make the ball move and a soccer ball cannot move because it is a kinetic energy it needs force to move.

The downward force of gravity and the upward force of air resistance on a ball?
0 meters per second squared As stated above, the ball will have zero acceleration due to the equal upward and downward forces, presuming the ball is moving or attempting to move in an upward or downward direction. The ball, in fact, will not be moving at all in this situation, but will be suspended in its position. If you are referring to an acceleration or motion in a direction that is not vertical, you will need to provide other information in order to get an answer.
Unbalanced forces in volleyball?
Unbalanced forces are important in order to move anything. An object under balanced forces does not move. For example as you sit in your chair reading this, gravity is exerting a force on your body downwards but your chair balances this force by exerting a force upwards on you that is equal and opposite to the force of gravity. These two forces oppose each other and therefore you do not move. In tennis in order to change the direction of a tennis ball you need to exert a net force(an unbalanced force) in the direction you want the tennis ball to move. In tennis there are also unbalanced torques(a force acting at a distance from a pivot point) on the ball that cause the ball to spin. Hope that helps.
How fast does a ball move inside 1.48 specific gravity water?
the speed of the object (ball in this case) would depend on the force applied, but the higher the density of matter the more force would need to be applied to generate the same speed.
Why is having upper body muscular strength and endurance important?
it is important to have uper body strenth for volley ball because you need strenth for force and in volley ball you will need to put force into the ball.
If you need to move a load sideways an upward which simple machine could you use?
A block and tackle.
Which pulley system can make work easier?
A pulley halves the force required to lift a load, but doubles the length of rope or cable. So if you had a 10lb. weight attached to a rope, and were pulling the rope upward, you would need 10lbs. of force to lift it. However, if you had a pulley attached to a beam overhead, and were pulling down on the rope, you would only need 5lbs. of force to move the weight, but you would need to pull twice as much rope to get the weight to move the same distance.
If you throw a ball to your friend. will the ball exert a force against your hand?
Since you need to exert force on the ball to push it away from you, the ball will obviously push back (with a force that has the same magnitude, but is in the opposite direction). This is an example of Newton's Third Law.
Why do rockets move against the gravity towards the space?
Because the engines are designed, built, and installed the way they need to be in order to develop a force that's larger than the total weight of the spaceship AND direct the force upward. The whole purpose of this plan is to be able to move the ship up, off the Earth and out into space. You use exactly the same technique, when you use your leg muscles to develop a force that's larger than your total weight, and direct the force upward, in order to climb a ladder or walk upstairs. We all do. Personally, I think that must be where the aerospace engineers got the idea from.
To make something move what kind of force do you need?
You need Potential (stored) Energy
