**Distance**

Distance is a scaler quantity measured in meters and can be negative, positive or zero. It is based on the actual length (meters) between two objects, or on the line-of-sight value of the shortest distance (meters) between two objects.

**Temperature**

Temperature is a measure of thermal energy. The SI unit is kelvin, the K. The Imperial unit is °F (or °C) and it varies from absolute zero (0 K) to 373 K. Temperature is a measure of thermal energy. The unit kelvin is used in the metric system. The kelvin is the same size as the degree Celsius, so an increase of one kelvin is the same as an increase of one degree Celsius. The same applies for Fahrenheit, but just converted to degrees. 0°C = 32°F 99°C = 212°F It is a logarithmic scale. The size of one kelvin is the same as a degree Celsius. A 10°C increase from room temperature is the same as a 10 K increase from absolute zero. The absolute temperature is the actual temperature and no other temperature is known to be absolute. The absolute zero is the coldest temperature theoretically possible. It is 0 K = -273.15°C or -459.67°F. It is the point at which all thermal energy is removed.

**Time**

If you consider what time is made of, it’s just the sequence of events. We can measure time by counting or by using a clock. Time is a tricky thing to understand but can be explained using a few ideas. First time is an interval and interval means distance. So time just represents a distance between one event and another. The other theory is that time is a measure of quantity of change. So this quantity of change is measured by different events. Now talking about what time really is can lead to some really interesting questions:

**1.** What is space?

**2.** What happens when you go back in time?

**3.** Is there a beginning? An end?

**4.** Is there infinite time?

**5.** Is there a creator?

**Weight**

Weight is a measurement of how much gravity is pulling down on something. On Earth, we weigh much more because the gravity is much higher. This is why they put people in centrifuges to make them feel like they weigh less. On the moon, there is much less gravity, so you would weigh less than when you’re on Earth. In fact, if you weigh 100 pounds on Earth, you would weigh 38 pounds on the moon!

**Area**

Area is the space that a three-dimensional object takes up (the magnitude of the area is the number of square units it contains). In physics, the SI unit of area is the square metre (m2). In mathematics, the area of a rectangle is calculated by multiplying its base by its height, and this equation is represented by the letter A.

**Speed**

Speed is defined as the rate of motion or travel of something that moves. Speed is important because it allows you to get where you are going as fast as possible. This is extremely important on the road, as the faster you drive, the less time you spend with your life in danger. It is also important to note, on the topic of speed, that in physics, the faster you go, the more mass you carry, therefore, the more you will weigh.
