Field Forces

Front

What is a field force?

Back

A field force is a force that acts at a distance without direct contact, such as gravitational, electric, and magnetic forces.

Front

What is gravitational force?

Back

Gravitational force is an attractive force that pulls objects toward each other, proportional to their masses and inversely proportional to the square of the distance between them.

Front

What is electric force?

Back

Electric force is the force between charged objects, which can be attractive or repulsive depending on the types of charges involved.

Front

What is magnetic force?

Back

Magnetic force is the attraction or repulsion between magnetic poles, where like poles repel and opposite poles attract.

Front

What is the difference between attractive and repulsive forces?

Back

Attractive forces pull objects together, while repulsive forces push objects apart.

Front

What is the role of Earth's magnetic field?

Back

Earth's magnetic field protects the planet from harmful solar radiation and helps in navigation.

Front

What happens when two negatively charged objects are brought close together?

Back

They repel each other due to the electric force acting between them.

Front

What is the significance of the Earth's magnetic poles?

Back

The Earth's magnetic poles can flip, which has implications for navigation and animal migration.

Front

What is the relationship between mass and gravitational force?

Back

The gravitational force increases with greater mass and decreases with greater distance between objects.

Front

What is an example of a field force in everyday life?

Back

An example of a field force is the gravitational pull that keeps us grounded on Earth.
