What is net force?

Back

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

Front

How do you calculate net force when two forces act in opposite directions?

Back

Subtract the smaller force from the larger force and indicate the direction of the larger force.

Front

What is frictional force?

Back

Frictional force is the force that opposes the motion of an object when it is in contact with another surface.

Front

What is the relationship between force and motion?

Back

An unbalanced force acting on an object causes it to accelerate in the direction of the net force.

Front

What are the characteristics of stars based on temperature and brightness?

Back

Stars can be classified based on their temperature (hotter stars are generally brighter) and their brightness (luminosity).

Front

What is the tilt of the Earth's axis and its effect on seasons?

Back

The tilt of the Earth's axis (approximately 23.5 degrees) causes seasonal changes as different parts of the Earth receive varying amounts of sunlight throughout the year.

Front

What happens to seasonal changes if the Earth's axis is upright?

Back

If the Earth's axis were perfectly upright, there would be no significant seasonal changes, leading to a more uniform climate.

Front

What are metalloids?

Back

Metalloids are elements that have properties of both metals and nonmetals, often used in semiconductors.

Front

How can materials be classified based on their properties?

Back

Materials can be classified as metals, nonmetals, or metalloids based on their physical and chemical properties.

Front

What is an action-reaction force pair?

Back

An action-reaction force pair is a pair of forces that are equal in size, but opposite in direction, acting on two different objects.
