In physics, force is a push or pull on an object. A force can cause an object to accelerate, slow down, remain in place, or change shape. How to Measure Force The unit of measure for force is the newton which is abbreviated as "N". One newton is the force needed to accelerate one kilogram of mass by one meter per second squared (N = 1 kg·m/s2).

10. Q: If you apply a net force of 3 N on 100 g-box, what is the acceleration of the box? D: 30 m/s2-----11. Q: Which is true from Newton's Third law of motion? B: For every action force there is an equivalent reaction force in the opposite direction.-----12. Q: What is the net force on 200 g ball when it hits a wall with acceleration of 10 m ...

Spike : A type of attack where the ball is hit down over the net with good force and speed. Strong side : The left side of the court. It's call this because most players are right handed and it's easier to attack from this side for a right hander. Tip : A soft hit attack used to get the ball over the net quickly. Weak side : The right side of ...

a 2 + b 2 = c 2 a 2 + 12 2 = 15 2 a 2 + 144 = 225 Subtract 144 from each side to get: 144 - 144 + a 2 = 225 - 144 a 2 = 225 - 144

A force is anything that can change the state of motion of an object, like a push or a pull. You use force when you push a letter on the computer keyboard or when you kick a ball. Forces are everywhere. Gravity acts as a constant force on your body, keeping you secure on planet Earth so you don't float away.

Simple Machines are basic mechanical devices for applying a force and doing work. More complex machines are made up of a bunch of simple machines. There are 6 basic types of simple machines: Lever The lever is made up of a straight rigid object like a board or a bar which pivots on a turning point called a fulcrum.

The puck is not aimed at the net. The puck must get all the way to the other end of the rink without a defender being able to touching it. This is up to the linesmen to determine. If an offensive player touches the puck before or just after it hits the other end of the rink, there is no icing.
