What is the relationship between instantaneous speed and instantaneous velocity?

Physics
1 answer:
Natalija [7]2 years ago
4 0

Answer:

Instantaneous speed is a scalar quantity.

Instantaneous velocity is a vector quantity.

Consider an object moving at a constant speed in a circle.

There is no change in speed as the object continues in a circular motion.

The acceleration however is

a = v^2 / r    because a vector representing the object is continually changing direction and the change in velocity is not zero as time increases.

What will happen when an object is not in equilibrium
r-ruslan [8.4K]

Answer:

Explanation:

25) Electrical -> thermal. In a toaster, there is a resistance through which current flows. Due to the Joule effect, the current flowing through the resistor causes an increase of temperature of the resistor itself, therefore the energy of the current (electrical) is converted into thermal energy, which is then used to heat the toast.

Which velocity graph shows the car moving toward the right (away from the origin) at a steady (constant) velocity? 
slega [8]

Explanation:

\text{Velocity is defined as the average displacement per unit time.}

\text{Since the car is moving at a steady velocity, the velocity does not change over time, it shows a horizontal line on the }v-t\text{ graph}

\text{Therefore, only option 2,5,8 matches this requirement.}

\text{Since the car is moving to the right, which is defined as the positive direction in this question, the velocity (}v\text{) is also positive.}

\text{Therefore, only option 5 is correct.}
