What is the difference between speed, velocity, and acceleration?
Speed, Velocity, & Acceleration in Physics
Speed is how fast an object is traveling with no specified direction. Velocity is the speed of an object in a specific direction. Acceleration is the rate of change in an object's velocity over time.
speed, velocity and acceleration physics
Speed: the rate at which an object is moving measured in units of distance per unit of time
Velocity: the speed of an object in a given direction. Velocity is represented by an arrow with a magnitude (size) and a direction
Acceleration: the rate of change of velocity with respect to time. It is measured in units of meters per second squared (m/s2)
How does increasing speed affect acceleration?
- It has no effect
- It increases acceleration
- It decreases acceleration
- It depends on the type of speed
Did you know?
Acceleration is the rate of change of velocity over time, and it can be calculated by dividing the change in velocity by the change in time. Constant acceleration is when an object's velocity increases evenly over a period of time.
What factors can affect the speed, velocity, and acceleration of an object?
How does velocity differ from speed and how is it calculated?
Think of an example of speed, velocity, and acceleration in everyday life. How do these concepts work together?
