Question 7 of 15

7. The time rate of change of displacement is called velocity. As distance is to displacement, so speed is to velocity: the crucial difference between the two is that speed is a scalar and velocity is a vector quantity. In everyday conversation, we usually say speed when we talk about how fast something is moving. However, in physics, it is often important to determine the direction of this motion, so you’ll find velocity come up in physics problems far more frequently than speed.

If a body covers a displacement of 50 meters in 10 seconds. What is the velocity of the object?
A.
B.
C.
D.

These practice tests are part of our GED online prep. Taking practice tests is very important because they indicate what your knowledge gaps are.

Taking practice tests is very important because they indicate what your knowledge gaps are.

It’s important that you know what your weak points are so you can focus on learning these topics.

Recent GED graduates have some good advice for you: don’t try to learn for all four GED tests at once.

You are allowed to take one of the four GED tests at a time, so prepare for one subject area, take that test, and move on to next subject field.

When preparing for the GED test, the most common slipup is forgetting to block some time for learning.

Postponement and pretexts are your biggest enemies. Please adopt a learning schedule and stick to it.

The second common mistake that leads to failing the GED test is the fact that students spend too much time on one question and end up not making it through the whole test.

Time management is one of the biggest stumbling blocks to passing the GED test.
