What is the difference between velocity and speed?
Velocity includes direction, while speed does not.
Which type of motion formula helps scientists understand an object's motion with respect to a frame of reference?
Velocity formula
Why might it feel like the motion on the ground is at 0 miles per hour despite significant Earth movements?
Motion is always relative to a frame of reference.
Why are velocity and speed often interchangeably used in layman's terms?
The layman's understanding simplifies complex concepts.
What is the main characteristic that differentiates average velocity from instantaneous velocity?
Time taken to calculate
What is the main difference between instantaneous speed and average speed?
Instantaneous speed accounts for the movement of an object at a specific moment, while average speed calculates the change in distance over a period of time.
What does acceleration measure?
Acceleration measures the change in velocity over time.
How can average acceleration be calculated if the initial and final velocity and time are known?
Divide change in velocity by change in time.
According to Newton's laws, what is the relationship between force and acceleration?
Force equals mass times acceleration.
