Physics: Ticker Tape and Displacement-Time Graphs

A ticker tape timer is a device that records the position of a moving object at regular intervals. What does a larger distance between dots on a ticker tape diagram indicate?

A horizontal line on a displacement-time graph represents an object that is at rest.

What does the slope of a velocity-time graph represent?

A ______ slope on a displacement-time graph indicates a positive velocity.

Match the following graph characteristics with their corresponding meaning:

A ______ line on a velocity-time graph represents constant acceleration.

The slope of a displacement-time graph is equal to the ______ velocity of the object.

On a velocity-time graph, a ______ slope indicates acceleration in a positive direction.

A ______ line on a displacement-time graph indicates that the object is at rest.

A ______ distance between dots on a ticker tape diagram indicates that the object was moving slowly during that time interval.

On a displacement-time graph, a ______ slope represents a faster velocity.

A ______ slope indicates a slower velocity on a displacement-time graph.

A ______ line on a velocity-time graph represents constant velocity.

Ticker Tape Timer and Diagrams

A ticker tape timer places a tick on a tape at regular time intervals.
A ticker tape diagram shows an object's motion with dots on a tape.
The distance between dots represents the change in position over a time interval.
Larger distances between dots mean faster motion; smaller distances mean slower motion.
Equal distances between dots indicate constant velocity.
Gradual decrease in dot spacing shows deceleration; gradual increase shows acceleration.

Displacement-Time Graph

Plots displacement versus time.
A straight line represents constant velocity.
The slope represents average velocity (displacement/time).
A positive slope indicates motion in a positive direction.
A negative slope indicates motion in a negative direction.
A horizontal line indicates the object is at rest.
A steeper slope represents a faster velocity.
A curved line indicates changing velocity (acceleration).

Velocity-Time Graph

Plots velocity against time.
A straight line represents constant acceleration.
A horizontal line indicates constant velocity.
A downward slope represents constant deceleration.
The slope indicates the direction of acceleration (positive for positive acceleration, negative for negative acceleration).
Deceleration in a positive direction is represented by a negative slope on a velocity-time graph, and vice-versa.

Graph Interpretation

Graphs show speed, velocity, and acceleration from slopes.
Steep slopes indicate faster velocities.
Shallow slopes indicate slower velocities.
Curved or changing slope lines indicate acceleration.
The direction of the slope on a velocity-time graph indicates the direction of acceleration.

This quiz covers the principles of ticker tape timers and diagrams, as well as displacement-time graphs. It highlights how these tools represent an object's motion and velocity. Understand the key concepts such as motion intervals and graphical representations of velocity.
