Do both speed and velocity have a direction?
The direction of the velocity vector is simply the same as the direction that an object is moving. Note that speed has no direction (it is a scalar) and the velocity at any instant is simply the speed value with a direction.
What must an answer for Velocity include?
Calculating Average Velocity It represents velocity only if the answer also includes the direction that the object is traveling. Note that the answer is given in the SI unit for velocity, which is m/s, and it includes the direction that the dog is traveling.
What is the change in velocity?
Acceleration: The rate of change of velocity is acceleration. Like velocity, acceleration is a vector and has both magnitude and direction. For example, a car in straight-line motion is said to have forward (positive) acceleration if it is speeding up and rearward (negative) acceleration if it is slowing down.
Why is velocity 0 at the peak?
Answer: 0 m/s. The instantaneous speed of any projectile at its maximum height is zero. Because gravity provides the same acceleration to the ball on the way up (slowing it down) as on the way down (speeding it up), the time to reach maximum altitude is the same as the time to return to its launch position.
What is the max acceleration?
First that the maximum acceleration is dependent on the coefficient of friction. If μs = 1, then the maximum acceleration would be 9.8 m/s2. Of course, for real humans, they can’t have an acceleration this high for very long.
Why is top speed important?
It was subsequently concluded that being able to reach higher maximum velocities improves an athlete’s ability to hit better times at any given distance. That maximum velocity training is critically important for enhancing overall sprint performance. 2. Increasing top speed enhances conditioning.
How do you determine maximum speed?
The formula for speed is simply v(0)t. 19.8*15.9= 314.82 m/s for the maximum speed.
