Velocity
Velocity is a measure of the speed and direction of an object's movement. It is a vector quantity, which means it has both magnitude (speed) and direction. The formula for calculating velocity is:
Velocity = Displacement / Time
Where:
- Velocity is the speed and direction of the object
- Displacement is the change in position of the object
- Time is the duration over which the displacement occurs
Factors Affecting Velocity
Several factors can affect an object's velocity:
- Force: The application of force can change the velocity of an object.
- Direction of Motion: Changing the direction of motion will change the velocity even if the speed remains constant.
- Friction: Friction with the surroundings can reduce the velocity of an object.
Units of Measurement
Velocity is typically measured in units such as meters per second (m/s) or kilometers per hour (km/h).
Study Guide
Here are some key points to remember about velocity:
- Velocity is a vector quantity, meaning it has both magnitude and direction.
- The formula for velocity is velocity = displacement / time.
- Factors such as force, direction of motion, and friction can affect an object's velocity.
- Velocity is typically measured in units such as meters per second (m/s) or kilometers per hour (km/h).

LIFE SCIENCE
From Molecules to Organisms: Structures and Processes
Create representations to explain the unique and diverse life cycles of organisms other than humans (e.g., flowering plants, frogs, butterflies), including commonalities such as birth, growth, reproduction, and death.
Unity and Diversity
Construct an argument from evidence to explain the likelihood of an organism’s ability to survive when compared to the resources in a certain habitat (e.g., freshwater organisms survive well, less well, or not at all in saltwater; desert organisms survive well, less well, or not at all in woodlands).
Create models that illustrate how organisms and their habitats make up a system in which the parts depend on each other.
