Unbalanced Forces

• When two or more forces act on an object causing the object to accelerate.

• When forces acting on an object are equal in size and opposite in direction.

• When an object is at rest and no forces are acting on it.

• When a single force acts on an object causing it to move.

Products of cellular respiration

• Carbon dioxide (CO₂), water (H₂O), and ATP

• Oxygen (O₂), glucose (C₆H₁₂O₆), and ATP

• Carbon monoxide (CO), water (H₂O), and glucose (C₆H₁₂O₆)

• Nitrogen (N₂), water (H₂O), and ATP

Heterotroph

• An organism that can produce its own food using sunlight.

• An organism that cannot make its own food and gets energy from other organisms.

• An organism that primarily feeds on plants.

• An organism that can survive without any food source.

Photosynthesis

• A process by which plants, algae, and some bacteria create their own food using energy from the Sun.

• A method of cellular respiration in animals.

• A technique used by fungi to decompose organic matter.

• A way for plants to absorb nutrients from the soil.

Cellular respiration is a process by which cells use oxygen to obtain energy from food.

• A process by which cells use oxygen to obtain energy from food.

• A method for plants to convert sunlight into energy.

• A way for cells to reproduce and grow.

• A technique for breaking down waste products in cells.

Chloroplast

• An organelle in the cells of some autotrophs where photosynthesis takes place.

• A type of cell that is responsible for cellular respiration.

• A structure that provides support and protection to plant cells.

• An organelle involved in protein synthesis.

Velocity

• A measure of the speed of an object in a straight line.

• A quantity that measures the rate at which the position of an object changes in time.

• The distance traveled by an object in a given time period.

• The speed of an object in relation to another object.

Displacement

• The total distance traveled regardless of direction.

• The length and direction of a straight line between two locations or positions.

• The change in position of an object over time.

• The distance covered by an object in a specific direction.

Law of Conservation of Energy

• can be increased by external forces

• is only applicable in closed systems

Byproduct of cellular respiration

• Oxygen and glucose.

• Carbon dioxide and water.

• Nitrogen and ammonia.

• Hydrogen and sulfur.
