What is the chemical formula for baking soda?

Back

NaHCO₃

Front

How many atoms are in one molecule of baking soda (NaHCO₃)?

Back

6

Front

What is a divergent plate boundary?

Back

A tectonic plate boundary where two plates move away from each other, often resulting in volcanic activity and the formation of new crust.

Front

What is the formula to calculate acceleration?

Back

Acceleration (a) = Net Force (F) / Mass (m)

Front

What is the approximate acceleration of a 51.5 kg bookshelf pushed with a net force of 67 N?

Back

1.3 m/s²

Front

What does Newton's first law state?

Back

An object at rest stays at rest, and an object in motion stays in motion at a constant velocity unless acted upon by a net external force.

Front

What happens to a steel ball in a box that suddenly stops according to Newton's first law?

Back

The ball continues rolling forward at the same speed due to inertia.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is the relationship between force, mass, and acceleration?

Back

According to Newton's second law, Force = Mass × Acceleration (F = m × a).

Front

What is a plate boundary?

Back

A region where two tectonic plates meet, leading to geological activity such as earthquakes and volcanic eruptions.
