TYPES OF FORCE

The type of force that holds atoms and their particles together.

• Nuclear

• Magnetic

Caused when an object rubs against other.

• Friction.

• Gravity.

The force that keeps you walking on earth instead of floating to space.

• Gravity.

• Nuclear.

Opposite poles of a magnet:

• Attract.

• Repel.

Similar poles of a magnet:

• Attract.

• Repel.

Once upon a time, there was a man called Isaac Newton. He was passionate about studying the forces of nature. One day, he saw an apple falling from a tree and he got curious about that. He thought that there must be some force  acting on falling objects- like apples-. After that, he discovered the force, he gave it a name! What name did he give to such force?

• Friction

• Nuclear

• Gravity

• Magnetic

Alejandro was playing with magnets when he realized that when trying to face the two equal poles of the magnets, something fascinating happened. What happened and why?

• The magnets attracted each other due to the magnetic force.

• The magnets repelled each other due to the magnetic force.

Look at the picture. How does the friction act on an object?

• It acts on the same direction of the applied force.

• It acts on the opposite direction of the applied force.

If there was no friction, and you kicked a ball, when would it stop?

• It would never stop.

• It would stop until it hits another object.

Do they need more or less friction?

• More friction

• Less friction
