Electromagnetic Force Inv. 1

Front

What is electromagnetic force?

Back

Electromagnetic force is one of the four fundamental forces of nature, responsible for the interactions between charged particles. It can attract or repel objects depending on their charges.

Front

What is a balanced force?

Back

A balanced force occurs when two forces acting on an object are equal in size but opposite in direction, resulting in no change in motion.

Front

What is an unbalanced force?

Back

An unbalanced force occurs when two forces acting on an object are not equal, causing the object to accelerate in the direction of the stronger force.

Front

What is net force?

Back

Net force is the overall force acting on an object after all the individual forces are combined. It determines the object's motion.

Front

What unit is used to measure force?

Back

The unit used to measure force is the Newton (N).

Front

How does friction affect motion?

Back

Friction is a force that opposes motion between two surfaces in contact. It can slow down or stop moving objects.

Front

What happens to an object at rest when balanced forces act on it?

Back

An object at rest will remain at rest when balanced forces act on it.

Front

What happens to a moving object when unbalanced forces act on it?

Back

A moving object will change its speed or direction when unbalanced forces act on it.

Front

What is the effect of gravity on objects?

Back

Gravity is a force that pulls objects toward each other, giving weight to objects and causing them to fall toward the Earth.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. An object at rest stays at rest, and an object in motion stays in motion unless acted upon by an external force.
