Hello There!

If you add together all of the forces exerted on a object and get a non zero value that is called the "NET FORCE" of the object

If you add together all of the forces acting on an object, the sum is called the NET FORCE on the object.

It might or might not be zero.  If it's NOT zero, then you know immediately that the object must be accelerating ... either its speed, or its direction, or both are changing.

what is the speed of a softball that travels 20m in 2secs

speed = 20/2 = 10 m/s

the design of a ski jumping suit involves a trade-off between giving the skiers lift to get higher jumps and ensuring the skier does not face a lot of drag before the jump itself. an expansive suit may to lift the skier higher, but at the same time, it will also increase the air resistance. higher air resistance as the skier goes down the slope limits the speed of the jump. a big suit also increases the risk of losing balance or control, especially if there's a strong gust of wind. while technologically enhanced suits a lot, clothing is not the only factor in a ski jumper’s success. gathering speed while skiing down the slope, ensuring good speed on the ramp, and maintaining good body posture and form in the air all contribute to a ski jumper's success.
