CHAPTER 6 FORCE AND PRESSURE PART 3 (EFFECTS OF FORCES)

CHAPTER 6 FORCE AND PRESSURE PART 3 (EFFECTS OF FORCES)

​In today's lesson, you will be able to...

1. Describe magnetic forces

2. ​Describe THREE ways forces affect objects

Let's begin the lesson!​

​Some starter questions first...

Multiple Choice

What would happen when you PUSH the pedals harder (with a BIGGER force)?

• The cyclist will get slower

• The cyclist will stop

• The cyclist will be cycling faster

• The cyclist will slow down

Multiple Choice

What happens to the balloon when you blow into it?

• Nothing happens

• The balloon will shrink

• The balloon will fall

• The balloon will increase in size

Multiple Choice

What happens to the dough when you apply force with your hands?

• The dough will not change shape

• The dough changes shape when you push or pull the dough

• The dough will just have one shape even though you push and pull

• The dough remains the same shape

​Ok. Lets start the lesson

MAGNETIC FORCES​

​Magnetic force

​What is a magnetic force? Look at the pictures below

​

​

​

​

​

​

​

​

• ​​UNLIKE poles ATTRACT

• LIKE poles ATTRACT​

​

​Attraction

​The North pole of a magnet will be ATTRACTED to the South pole of a magnet.

​

​UNLIKE poles attract.

Repulsion

​The North pole of a magnet will REPEL to the North pole of a magnet.

​It is the same for South pole will REPEL the South pole of magnet.

​

​LIKE poles attract

Multiple Select

What are the RULES for magnetic forces? Tick the correct answers (there is more than one answer)

• UNLIKE poles ATTRACT

• UNLIKE poles REPEL

• LIKE poles ATTRACT

• LIKE poles REPEL

Multiple Choice

What will happen when the North pole of a magnet gets close to another North pole of magnet?

• Repel

• Attract

Lets move on to:

EFFECTS OF FORCES​

​Study the picture carefully

Forces affect objects in THREE ways

1. A force can change the SPEED of an object (to make the object faster or slower)

2. ​A force can change the DIRECTION of an object

3. ​A force can change the SHAPE of an object

​A force can change the SPEED of an object

​A cyclist that pushes harder on the pedals, makes the bicycle go faster.

​A force can change the DIRECTION of an object

​A force can be used to change the direction of an object, like a footballer on the football.

​

​A force can also STOP a moving object!

​A force can change the SHAPE of an object

​We can apply a force by pushing or pulling an object and it can change the shape of the object.

​Remember, a force will NOT change the MASS of an object. Mass is the weight of object.

​We can apply a force by pushing or pulling an object and it can change the shape of the object, but it will NOT change the MASS of the dough.

​The dough does not get heavier or lighter!!

That's it! Question time​
