2024-25 Common Assessment ( August)

Front

What are electromagnetic waves?

Back

Electromagnetic waves are waves that can transfer energy through a vacuum or space without the need for a medium.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state, which can be converted into other forms of energy.

Front

What type of energy is produced when fossil fuels are burned?

Back

Thermal energy is produced when fossil fuels like coal, oil, and natural gas are burned.

Front

What effect does a rough surface have on the motion of an object?

Back

A rough surface opposes the force applied to an object, increasing friction and resistance.

Front

What is waste generation?

Back

Waste generation refers to the process of producing waste materials, often as a result of human activities.

Front

What is the environmental impact of synthetic materials?

Back

Synthetic materials can take a long time to decompose, leading to waste accumulation and environmental pollution.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, which depends on its mass and velocity.

Front

How does potential energy change when an object is in motion?

Back

As an object moves downward, its potential energy decreases while its kinetic energy increases.

Front

What is the relationship between energy and work?

Back

Work is done when energy is transferred to an object, causing it to move or change position.

Front

What is the principle of conservation of energy?

Back

The principle of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.
