Physics Midterm Review

Front

What is the horizontal component of a projectile's velocity independent of?

Back

The vertical component.

Front

If an object is moving with a constant, positive velocity, how does the graph of position vs. time appear?

Back

A straight line with a positive slope.

Front

How do you express 34567.01 in scientific notation with three significant figures?

Back

3.46 x 10^4.

Front

What is the average velocity of an object if it moves from 15 to 40 seconds and the result is -4 m/s?

Back

The average velocity is -4 m/s.

Front

Calculate the total distance and displacement for Betsy the bee traveling between flowers A, B, and D.

Back

Distance = 15.4 m, Displacement = 4 m.

Front

Define displacement in physics.

Back

Displacement is the shortest distance from the initial to the final position, including direction.

Front

What is the difference between distance and displacement?

Back

Distance is the total path length traveled, while displacement is the straight-line distance between start and end points.

Front

What does a straight, horizontal line on a position vs. time graph indicate?

Back

It indicates that the object is at rest.

Front

What is the formula for average velocity?

Back

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

Front

What is scientific notation and why is it used?

Back

Scientific notation is a way to express large or small numbers conveniently, using powers of ten.
