Exploring Forces in Our World

Front

What is an Applied Force?

Back

An Applied Force is a force that is applied to an object by a person or another object. It is used to lift, push, or pull an object.

Front

What is a Frictional Force?

Back

A Frictional Force is a force that opposes the motion of an object. It acts parallel to the surfaces in contact and can slow down or stop moving objects.

Front

What is a Gravitational Force?

Back

Gravitational Force is the force of attraction between two masses. It pulls objects toward each other, such as the Earth pulling objects toward its center.

Front

What is a Magnetic Force?

Back

A Magnetic Force is a non-contact force that can attract or repel magnetic materials. It acts at a distance without physical contact.

Front

What is the role of Frictional Force in everyday life?

Back

Frictional Force helps objects stay in place, allows us to walk without slipping, and enables vehicles to stop when brakes are applied.

Front

What is the difference between contact and non-contact forces?

Back

Contact forces require physical contact between objects (e.g., Frictional Force), while non-contact forces act at a distance without direct contact (e.g., Gravitational and Magnetic Forces).

Front

How does Gravitational Force affect objects on Earth?

Back

Gravitational Force pulls objects toward the Earth, giving them weight and causing them to fall when dropped.

Front

What happens when an Applied Force is greater than Frictional Force?

Back

When an Applied Force is greater than the Frictional Force, the object will move in the direction of the applied force.

Front

Can Magnetic Force act on non-magnetic materials?

Back

No, Magnetic Force only acts on magnetic materials like iron, nickel, and cobalt.

Front

What is the effect of Frictional Force on a moving bicycle?

Back

Frictional Force slows down the bicycle when brakes are applied, helping to bring it to a stop.
