MAGNETIC FORCE Magnetic materials such as iron, steel, cobalt and nickel. A magnet has a north and a south pole with like poles repelling and unlike poles attracting. Just like a magnet, the Earth has a magnetic field with its South Pole under Earth's magnetic North Pole.

Here are the answers to your questions: 1.1 How can the soccer player stop the movement of the ball? The soccer player can stop the movement of the ball by applying a force to it in the opposite direction of its motion, for example, by kicking it or trapping it. 1.2 Explain how the player can cause the ball to change direction. The player can cause the ball to change direction by applying a force to it at an angle to its current path of motion. 2.1 What are the two poles in a magnet? The two poles in a magnet are the North pole and the South pole. 2.2 What is observed when the same poles of a magnet are brought against each other? When the same poles of a magnet are brought against each other, they repel each other. 2.3 Looking at the magnets, what do you observe about the iron filings? The iron filings arrange themselves in specific patterns around the magnets, showing the magnetic field lines. 2.4 What do you think the iron filings are made of? The iron filings are made of iron or another ferromagnetic material. 2.5 Magnets are examples of non-contact forces because they (create/don't create) ______ magnetic field around them. Magnets are examples of non-contact forces because they create a magnetic field around them. 3.0 Explain by referring to the 2.3 why non-contact forces are also called field forces. Non-contact forces are called field forces because they act on objects over a distance through a region of influence called a field, such as a magnetic field (as shown by the iron filings in 2.3) or a gravitational field, without direct physical contact. 3.1 Mention the type of applied force in each of the diagrams: A: Pushing* B: Pulling* C: Pulling* (Tug of war) D: Pushing* 3.2 Describe the effect of the force applied in the following diagrams: A: The force causes the wheelbarrow to move and increase speed*. B: The force causes the cart to move and increase speed*. C: The force causes movement, and can change speed or stop movement* depending on the net force. D: The force causes the swing to move and increase speed*. 4. A force can stop movement, change shape, increase speed or slow down an object. Refer to the diagram and identify the mentioned effects of a force. In diagrams A, B, and D, the force causes the object to move and increase speed*. In diagram C (tug of war), the force causes movement, and can either increase speed, slow down, or stop movement* if the forces are balanced.
