Why might someone want to change the direction of a force they apply?
Someone might want to change the direction of a force they apply to adjust the motion or orientation of an object, to overcome an obstacle, to control the speed or velocity of something, or to change the position of an object within a system.
How do you slow down a ball?
To slow down a ball, you can apply friction by rubbing it against a surface, increase air resistance by opening a parachute or adding drag-inducing features, or employ a magnetic field to create resistance. Each method can help reduce the speed and velocity of the ball effectively.
How can I launch a ball in the pool effectively?
To launch a ball effectively in the pool, stand at the edge of the pool with your feet shoulder-width apart. Hold the ball with both hands, bring it behind your head, and then throw it forward with a strong and smooth motion. Aim for a spot in the water where you want the ball to land. Practice your technique to improve accuracy and distance.
Why that the slowing down of moving object is considered to be a form of acceleration?
Acceleration is defined by physics as the rate of change of velocity over time. a = dv/dt As time changes, any change in velocity results in a change in acceleration. That change can be positive or negative. If you want to know why, its because acceleration and velocity are vectors. A vector has a magnitude and a direction. The magnitude is the value, and the direction refers to the direction the object is traveling. An example when acceleration doesn't point in the same direction as velocity is when you throw a ball into the air. You throw it up, so the initial velocity is in the upward direction. However the acceleration due to gravity is downward. It will slowly decrease the upward velocity of the ball until it is zero. At that point the ball will start to fall downard and increase in velocity until it hits the ground.
A 41.8 gram golf ball is dropped from 1.41 meters and then bounces back to the exact same height what is the force in newtons exerted on the ball in the 0.012 seconds it was in contact with the floor?
Answer:1. ball falls from a height of 1.41m, so what is its momentum when it hits the floor? Well, assuming the ball falls on earth:mom = m.vacceleration = 9.8m/s/swhere m=mass of ball; V=velocity of ball when it hits the groundHow do we know what velocity it travels at when it hits the ground? We use uniform acceleration formulas (because the force due to grav is constant):v=u+a.t; S=u.t+(1/2).a.t^2; V^2=u^2 + 2.a.swhere s=displacment; u=inital velocity; v=final velocty; a=acceleration; t=timeSo which one applies? what do we know about the ball, and what do we want to find out?we know balls mass, inital velocity, which we'll say is 0. We know the acceleration is 9.8m/s/s.We want to know it final velocity, so we'll use V^2 = u^2 + 2.a.su=0soV^2 = 2.a.sthereforeV^2 = 2.(9.8m/s/s).(1.41m) = 27.636soV= root(27.636) = 5.26m/s (3.s.f)we know v, now we can work out momentum:v.m = (5.26m/s).(41.8/1000)kg (notice I have to put it in kg, not grams)0.2197kgm/sNow, this is the momentum the ball has at the moment it touches the ground, and because we know that the force exerted is equal to the rate of change of momentum and we know this change takes 0.012seconds to occur, and that the ball moves with the same velocty in the opposite direction:total change in mom = 2.(0.2197kgm/s) = 0.4394kgm/s, which takes 0.012sectherefore force = (0.4394kgm/s) / (0.012sec)36.62 newtons!Hopfully someone will jump in if I made some error somewhere.
In crispin the cross of lead why does john ball want england to change?

Where is inertia based on?
Inertia is the tendency to not want to change, or in simple words, to keep doing what you're already doing. That means when a ball is rolling down the hill, it has inertia; it does not want to stop rolling. However, the ball will eventually stop because of friction or an object acting as an obstacle.
Your dstt is in a different language can you change it?
on your menu screen go to a thing that looks like a wrench and that is your settings go to the network ball thing and it will asks for what language you want touch it and then it will change, if the games are in a different language you cant change it.
What is pull back in soccer?
The pull back is you are moving with ball in one direction and place your foot on top of the ball and quickly drag it back towards you if a defender is not allowing you to move forwards and you want to quickly change directions.
What do you shout in volley ball if you want to play the ball?
