Sometimes it speeds up and sometimes slows down. At a given instant time what we read from the speedometer is instantaneous speed. For example, a car moving with a constant speed travels to another city, it must stop at red lights in the traffic, or it should slow down when unwanted situations occur in the road.

In this lesson, you will learn more about motion in one dimension, meaning that an object is moving in a straight line: either forwards or backwards, up or down, left or right. An example of one-dimensional motion is the motion of the cars in the drag race video.

Instantaneous speed is found by taking the absolute value of instantaneous velocity, and it is always positive. Average speed is total distance traveled divided by elapsed time.

In the 1600s, physicist and astronomer Galileo Galilei tried to calculate the speed of light by measuring how long it would take a person to see a light from across a field. It didn’t work (light is way too fast to be measured this way), but Galileo did come up with the formula distance/time = average speed.

The average speed of an object is defined as the distance traveled divided by the time elapsed. Velocity is a vector quantity, and average velocity can be defined as the displacement divided by the time.

Average speed is defined as the total distance travelled by the time taken whereas average velocity is defined as the displacement by the time taken. Since speed is a scalar quantity, the average speed is also considered as a scalar quantity while velocity is a vector quantity.

distance travelled per unit time

There are two types of speed: result-speed and task-speed.

Time is defined as the duration in which all things happen, or a precise instant that something happens. An example of time is the Renaissance era. An example of time is breakfast at eight o’clock in the morning. An example of time is a date at noon next Saturday.

You need other skills in order to take that muscle and be able to compete at a higher level. And one of the most important skills is SPEED. You also need a good deal of speed because power is a blend of strength and speed. Power is your ability to throw all that muscular might into useful velocity.

10 Health Benefits of Speed Training That Go Beyond Faster Times

• A Stronger Stride.
• More Muscle.
• Better Fat Burn.
• Reduced Risk of Injury.
• Stronger Bones and Other Connective Tissues.
• Improved Running Economy.
• More Anaerobic Endurance.
• Better Balance and Proprioception.

A speedometer is a great example of instantaneous speed. The speed of light can also be written as 186,282 miles per second. The speed of sound in dry air is 343.2 meters per second. The escape velocity of Earth is the speed needed to escape from Earth’s gravitational pull.

Power foods: What to eat to up your immunity and run faster

• Coffee. Runners who had caffeine one hour before an eight-mile run improved their times by an average of 23.8 seconds, in a study reported in the Journal of Sports Science.
• White button mushrooms.
• Watermelon.
• Kale.
• Beetroot.
• Capers.
• Bran flakes.

The Fundamentals of Increasing Strength to Improve Speed

1. The Deadlift. The deadlift is one of the best exercises (in most cases) for improving total body strength, speed, and athleticism.
2. The Squat. The squat will assist in developing strength in an athlete’s quads, hip flexors, glutes, and hamstrings.
3. Sled Drags.
4. Step-Ups.
5. Pull-Ups.

If you’re training to be competitive in a race, for example, going faster will be key. But if you are looking to shed pounds, longer runs might be the best way to go. On the other hand, running longer distances is good for endurance and allows you to burn a substantial number of calories in a single workout.

The best way to breathe while running is to inhale and exhale using both your nose and mouth combined. Breathing through both the mouth and the nose will keep your breathing steady and engage your diaphragm for maximum oxygen intake. It also allows you to expel carbon dioxide quickly.

Here are some tips to keep in mind as you prepare to run for 30 minutes.

1. Find your place. Map out a few safe, scenic, flat, traffic-free routes that you can cover in various weather conditions and times of day.
2. Pace yourself.
3. Run relaxed.
4. Stay flexible.
5. Get distracted.
6. Fuel up for your workouts.
7. Get the plan.

A good goal for a beginner is to work your way up to being able to run 20 minutes at a time. It may take weeks, but once you can consistently run 20 minutes then you’re well on your way. Ultimately, if you have goals in distance running then you’ll want to work your way up to 60-minute long runs. Good luck!
