SEMESTER EXAM REVIEW

Front

What is the concentration of a solution?

Back

Concentration refers to the amount of solute (like vitamin C) present in a given volume of solvent (like water). It is often expressed as a ratio or percentage.

Front

What are natural satellites?

Back

Natural satellites are celestial bodies that orbit planets. The most common example is moons.

Front

What does Newton's first law of motion state?

Back

Newton's first law states that an object in motion will stay in motion unless acted upon by an external force. This is also known as inertia.

Front

What happens to a satellite if it loses gravity?

Back

If a satellite loses gravity, it will continue to move in a straight line instead of orbiting.

Front

What is displacement?

Back

Displacement is the length of a straight line between two points, regardless of the path taken.

Front

What is the solid core of a planet?

Back

The solid core is the innermost layer of a planet, which is typically composed of metals and is solid due to high pressure.

Front

What is the difference between speed and velocity?

Back

Speed is the distance traveled over time, while velocity includes both speed and direction.

Front

What is an example of a force that affects satellite motion?

Back

Gravity is a key force that affects the motion of satellites as they orbit around larger celestial bodies.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What is the role of water in a solution?

Back

Water acts as a solvent, dissolving solutes like salt or sugar to form a solution.
