Write a paragraph about pull.

Answer:A force can be described as a push or a pull. Pushes and pulls can be seen to act on objects when they begin to move, speed up, slow down or change direction.

The image gallery on this page shows children at play using push and pull actions to move objects. Children use push and pull all the time while at play. While playing, students learn to manipulate objects and materials and make observations about their actions.

Teachers may use this teaching resource over a number of lessons to explore and develop their students' understanding that a push or a pull affects how an object moves or changes shape.

Explanation:

In physics, we speak of forces applied to objects. This is all part of Newtonian mechanics. The key is that an object at rest will remain at rest unless a force acts on it, and an object in motion will continue in motion at the same speed (velocity) and in the same direction unless a force acts on it.

Forces can be categorized in various ways. A pull would be a force towards that which is pulling. A push would be a force away from that which is pulling.

Forces can also be categorized by whether contact is needed for the force to act on the object. An example of a pulling force with contact would be where I attach a rope to something and pull it towards me. Pulling can also be called attraction. An example of a pushing force with contact would be a billiard ball being hit by the cue ball and moving away from the cue ball. Pushing can be called repulsion.

There are also forces that act with no contact. The force of gravity is an attractive force only. Things fall towards the Earth when we let go of them due to gravity, and the earth stays in orbit around the sun instead of flying away in a straight line due to gravity. There is no gravity of repulsion, where objects are pushed apart due to their mass. Or at least, we haven't found one yet.

Electromagnetic force can attract (pull) or repel (push). Two magnet will attract from the north pole of one to the south pole of the other, but repel if the alignment is north-north or south-south.

Many forces can act at once, and forces come at odd angles, too. A cue ball will repel the ball it hits. But only if it hits straight on (with the line of travel of the cue ball the same as the line from the center of the cue ball to the center of the ball being hit) will the ball being struck move straight away from the cue ball. If the collision is at an angle, the push will occur, but it will be at an angle, and only some of the force will transfer.

What front does this symbol represent on a weather map?

1. Where is the water in the pot going?


2.How does E? Emulsion, the celebrity food scientist, define a physical reaction and what examples does he give?

Students were creating graphs to illustrate the energy transformations that occur as a roller coaster moves along a track. The letters A-D on Graph 1 represent the position of a roller coaster as it moves along a track. The numbers 1-4 on Graph 2 were supposed to represent the energy of the roller coaster at positions A-D, but the students got their data mixed up. How should the bars in Graph 2 be ordered so that they match to the energy of the roller coaster as it moves from position A to B to C to D?
