Unit 1-4 REVIEW

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It is measured in meters per second squared (m/s²).

Front

What is the formula for calculating acceleration?

Back

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

Front

What is the pH scale?

Back

The pH scale measures how acidic or basic a substance is, ranging from 0 (very acidic) to 14 (very basic), with 7 being neutral.

Front

What does a pH level lower than 7 indicate?

Back

A pH level lower than 7 indicates that a substance is acidic.

Front

What happens to glucose when it is heated?

Back

When glucose (C6H12O6) is heated, it breaks down into carbon and water.

Front

What is the mass of an object?

Back

Mass is a measure of the amount of matter in an object, typically measured in kilograms (kg).

Front

What is force?

Back

Force is a push or pull acting on an object, measured in newtons (N).

Front

How do you calculate the net force acting on an object?

Back

Net force is calculated by summing all the forces acting on an object, taking into account their directions.

Front

What is the relationship between mass and acceleration?

Back

According to Newton's second law, the greater the mass of an object, the less acceleration it will have for a given force.

Front

What is the significance of the unit 'Newton'?

Back

The Newton (N) is the unit of force in the International System of Units (SI), defined as the force required to accelerate a 1 kg mass by 1 m/s².
