Forces in Action with Models Assessment

Front

What is gravity?

Back

Gravity is a force that pulls objects towards each other. On Earth, it pulls everything towards the ground.

Front

What is an electromagnet?

Back

An electromagnet is a type of magnet that is created when electricity flows through a wire. It can be turned on and off.

Front

What happens when an electromagnet is turned off?

Back

When an electromagnet is turned off, it loses its magnetic force and objects that were being held by it may fall due to gravity.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object. It occurs when two surfaces rub against each other.

Front

What is magnetism?

Back

Magnetism is a force that can attract or repel certain materials, like iron, and is produced by magnets.

Front

What force is represented by arrows pointing down on a model of Earth?

Back

The arrows represent gravity, which pulls everything towards the center of the Earth.

Front

What are the two forces acting on a magnetic marble moving towards a magnet?

Back

The two forces are magnetic force (pulling the marble towards the magnet) and pulling force (which can be the force of the hand or another object).

Front

What is a model in science?

Back

A model is a representation of an object or system that helps us understand how it works.

Front

How does gravity affect objects on Earth?

Back

Gravity pulls objects towards the ground, making them fall if they are not supported.

Front

What is the role of friction in motion?

Back

Friction slows down or stops the movement of objects. It is important for walking and driving.
