Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or state. For example, a pendulum at its highest point has maximum potential energy.

Front

At which points does a pendulum have the greatest potential energy?

Back

A and C (the highest points of the swing).

Front

What is speed?

Back

Speed is the distance traveled per unit of time. It is a scalar quantity and does not have a direction.

Front

How do you determine which runner had the fastest speed?

Back

Compare the distances covered by each runner in the same amount of time.

Front

What is force?

Back

Force is a push or pull acting on an object, measured in newtons (N). It can cause an object to accelerate.

Front

If two forces act on an object in opposite directions, how do you find the resultant force?

Back

Subtract the smaller force from the larger force and apply the direction of the larger force.

Front

What is the resultant force on a box if a 10 N force is applied to the right and a 2 N force to the left?

Back

The resultant force is 8 Newtons to the right.

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants use sunlight to convert carbon dioxide and water into glucose and oxygen.

Front

What role does photosynthesis play in a food chain?

Back

Photosynthesis allows plants to produce energy, which is then transferred to herbivores and higher trophic levels in the food chain.

Front

What is respiration in biological terms?

Back

Respiration is the process by which cells convert glucose and oxygen into energy, carbon dioxide, and water.
