PHYS 2.1 - Motion in One Dimension

Front

What does a graph representing constant negative velocity look like?

Back

A straight line with a negative slope.

Front

Is displacement a vector or a scalar quantity?

Back

Displacement is a vector quantity.

Front

How do you convert hours to minutes?

Back

Multiply the number of hours by 60.

Front

What is the relationship between motion and a reference point?

Back

Motion is relative, requiring a fixed point to describe position.

Front

Define velocity in terms of displacement and time.

Back

Velocity is defined as displacement divided by time.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

What is the formula for calculating average velocity?

Back

Average velocity = (final position - initial position) / time interval.

Front

What is the significance of a zero slope on a position-time graph?

Back

A zero slope indicates that the object is at rest.

Front

How can you determine if an object is accelerating from a velocity-time graph?

Back

If the slope of the velocity-time graph is positive or negative, the object is accelerating.

Front

What does it mean for motion to be uniform?

Back

Uniform motion means an object moves at a constant speed in a straight line.
