What is the atomic number?

Back

The atomic number is the number of protons in the nucleus of an atom, which determines the element's identity.

Front

What does a satellite in orbit experience?

Back

A satellite in orbit experiences balanced forces, meaning the gravitational pull and the inertia of the satellite are equal.

Front

How is force measured?

Back

Force is measured in Newtons (N), which is the SI unit of force.

Front

What is net force?

Back

Net force is the overall force acting on an object after all the individual forces are combined.

Front

What is a force?

Back

A force is a push or pull on an object that can cause it to accelerate, change direction, or change shape.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is the formula for calculating force?

Back

Force (F) is calculated using the formula F = mass (m) × acceleration (a).

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion; it is directly related to mass.

Front

What is gravitational force?

Back

Gravitational force is the attractive force between two masses, which depends on their masses and the distance between them.

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces do not cause a change in motion, while unbalanced forces result in acceleration or a change in motion.
