Acceleration in One Dimension

Art10 CardsCreated 6 months ago

This deck covers key concepts related to acceleration in one-dimensional motion, including velocity changes, acceleration directions, and speed comparisons of moving carts.

What is the change in velocity?

The change in velocity is the difference between the initial and final velocity vectors of an object.

Definition
What is the change in velocity?
The change in velocity is the difference between the initial and final velocity vectors of an object.
How do you represent the change in velocity for a cart collision?
Draw vectors for each cart showing the difference in velocity before and after the collision, ensuring consistency in magnitude and direction.
What does the direction of average acceleration indicate?
It indicates the direction in which the velocity of an object is changing over a time interval.
How does the direction of average acceleration of cart A compare to cart B after collision?
The direction of average acceleration for each cart depends on the change in velocity vector direction for each cart.
What is a strobe diagram?
A strobe diagram shows the positions of moving objects at equal time intervals, helping to analyze motion.
At instant 3, is cart A speeding up, slowing down, or moving at constant speed?
This depends on the spacing of the positions in the strobe diagram; if the spacing increases, it's speeding up, if it decreases, it's slowing down.

This depends on the spacing of the positions in the strobe diagram; if the spacing increases, it's speeding up, if it decreases, it's slowing down.
How can you determine if cart B's speed is greater than cart A's at instant 3?
Compare the spacing between positions in the strobe diagram; greater spacing indicates higher speed.
What does equal spacing in a strobe diagram indicate?
Equal spacing indicates that the object is moving with a constant speed.
What does increasing spacing in a strobe diagram indicate?
Increasing spacing indicates that the object is speeding up.
What does decreasing spacing in a strobe diagram indicate?
Decreasing spacing indicates that the object is slowing down.
