What is a chemical change?

Back

A chemical change is a process where one or more substances are transformed into new substances with different properties, often indicated by the production of gas, formation of a precipitate, or color change.

What is a physical change?

Back

A physical change is a change that affects one or more physical properties of a substance without altering its chemical composition, such as changes in state (solid, liquid, gas) or dissolving.

Front

What indicates a chemical change in a reaction?

Back

Indicators of a chemical change include the production of gas, formation of a precipitate, color change, or temperature change.

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces occur when the net force acting on an object is zero, resulting in no change in motion. Unbalanced forces result in a net force that causes an object to accelerate.

Front

What is kinetic energy?

Back

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

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state, such as gravitational potential energy or elastic potential energy.

Front

What are transverse waves?

Back

Transverse waves are waves in which the motion of the medium is perpendicular to the direction of the wave's travel, such as light waves and waves on a string.

Front

What are longitudinal waves?

Back

Longitudinal waves are waves in which the motion of the medium is parallel to the direction of the wave's travel, such as sound waves.

Front

What is elastic potential energy?

Back

Elastic potential energy is the energy stored in elastic materials as the result of their stretching or compressing.

Front

What happens during an earthquake?

Back

During an earthquake, energy is released from the Earth's crust, causing seismic waves that can be felt on the surface.
