IPC 3rd six weeks test review

Front

What is the formula to calculate acceleration?

Back

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

Front

What is the unit of force in the International System of Units (SI)?

Back

Newton (N)

Front

What is the principle of conservation of momentum?

Back

In a closed system, the total momentum before a collision is equal to the total momentum after the collision.

Front

What does a horizontal line on a position-time graph indicate?

Back

The object is at rest.

Front

What is a sign of a chemical reaction?

Back

Rusting of iron.

Front

What is an indicator of a chemical reaction?

Back

Change in color.

Front

What is the mass of an object if a net force of 50 N results in an acceleration of 5 m/s²?

Back

Mass (m) = Force (F) / Acceleration (a) = 50 N / 5 m/s² = 10 kg.

Front

What happens to momentum in a collision between two objects?

Back

Momentum is conserved.

Front

What does a line with a positive slope on a position-time graph represent?

Back

The object is moving away from the starting point.

Front

What is the definition of a chemical reaction?

Back

A process that leads to the transformation of one set of chemical substances to another.
