Velocity Flashcards
What is motion?
Motion is the change in position of an object over time.
What is a frame of reference?
A frame of reference is a system for specifying the precise location of objects in space and time.
What is the difference between scalar quantity and vector quantity?
Scalar quantities have magnitude only, while vector quantities have both magnitude and direction.
What is the difference between distance and displacement?
Distance is the total path length traveled, while displacement is the shortest straight line from the initial to the final position.
What is the difference between speed and velocity?
Speed is a scalar quantity representing how fast an object is moving, while velocity is a vector quantity that includes direction.
What is the formula for speed?
Speed = Distance / Time
What is the difference between instantaneous speed and average speed?
Instantaneous speed is the speed at a specific moment, while average speed is the total distance divided by total time.
What does the slope of a distance vs. time graph represent?
The slope of a distance vs. time graph represents speed.
What is acceleration?
Acceleration is the rate of change of velocity over time.
What is the formula for acceleration?
Acceleration = (Final Velocity - Initial Velocity) / Time
What are the changes in acceleration?
Changes in acceleration include change in velocity (acceleration vs. deceleration) and change in direction.
What is acceleration due to gravity?
Acceleration due to gravity is the acceleration experienced by an object in free fall, approximately 9.81 m/s².
What does the slope of a velocity vs. time graph represent?
The slope of a velocity vs. time graph represents acceleration.
What are vectors in physics?
Vectors include displacement, velocity, and acceleration, which all have both magnitude and direction.
What are the units for distance/displacement?
The units for distance/displacement are typically meters (m).
What are the units for speed/velocity?
The units for speed/velocity are typically meters per second (m/s).
What are the units for acceleration?
The units for acceleration are typically meters per second squared (m/s²).
