10 Questions
Define average speed of an object.
Total distance traveled divided by time taken
What distinguishes velocity from speed?
Velocity includes both magnitude and direction; it is a vector quantity
When do average speed and average velocity have the same magnitude?
When the motion is all in one direction
Define instantaneous velocity.
The limiting value of the ratio ∆x / ∆t as ∆t approaches zero
What does it mean when a particle is said to be accelerating?
When the velocity of the particle changes with time
What is the difference between average speed and instantaneous speed?
Average speed is the total distance traveled divided by total time, while instantaneous speed is the magnitude of the instantaneous velocity.
Explain the concept of instantaneous velocity and how it relates to the limiting value of a ratio.
Instantaneous velocity is the velocity of an object at a specific instant in time. It is calculated as the limiting value of the ratio of change in position to change in time as the time interval approaches zero.
When does a particle have zero acceleration?
A particle has zero acceleration when its velocity remains constant over time.
How is velocity different from speed in terms of direction?
Velocity is a vector quantity that includes both magnitude (speed) and direction, while speed is a scalar quantity that only includes magnitude.
Explain the relationship between average speed and average velocity when the motion is not in a straight line.
When the motion is not in a straight line, average speed and average velocity may differ in magnitude and direction due to changes in the path taken.
Test your understanding of motion in a straight line, including topics like position, velocity, speed, acceleration, and one-dimensional motion with constant acceleration. Explore types of motion such as translational, rotational, and vibrational.
