Front

What is a balanced force?

Back

A balanced force occurs when two forces acting on an object are equal in size and opposite in direction, resulting in no change in motion.

Front

What is an unbalanced force?

Back

An unbalanced force occurs when two forces acting on an object are not equal, causing the object to accelerate in the direction of the greater force.

Front

What do organisms on trophic level 3 primarily consume?

Back

Organisms on trophic level 3 primarily consume herbivores, which are organisms that eat producers.

Front

What is velocity?

Back

Velocity is the speed of an object in a specific direction, expressed in units such as meters per second (m/s) with a directional component.

Front

What is the difference between a single atom and a molecule?

Back

A single atom is the smallest unit of an element, while a molecule is a group of two or more atoms bonded together, such as N2.

Front

What factors can increase the rate of dissolution?

Back

Factors that can increase the rate of dissolution include agitation (stirring), heating the solvent, and increasing the surface area of the solute.

Front

What is a producer in an ecosystem?

Back

A producer is an organism that can make its own food through photosynthesis or chemosynthesis, forming the base of the food chain.

Front

What is a herbivore?

Back

A herbivore is an organism that primarily eats plants and is typically found at the second trophic level in a food chain.

Front

What is a secondary consumer?

Back

A secondary consumer is an organism that eats primary consumers (herbivores) and is typically found at the third trophic level.

Front

What is the significance of direction in velocity?

Back

Direction is significant in velocity because it indicates the path along which an object is moving, distinguishing it from speed, which is scalar.
