Question

List the units of each of these: a. Force: b. Mass: c. Speed: d. Acceleration: e. Velocity: f. Time:

Answer 1

a. Force: Newton or
`k g m s^(2)`

b. Mass: kg

c. Speed: m/s

d. Acceleration:
`m / s^(2)`

e. Velocity: m/s

f. Time: seconds (s)

Step-by-step explanation:

a) Force:

In science, force push or pull of object whose mass (m) changes speed (to accelerate). The force represents as a vector, which means it has both magnitudes and the directions. The unit uses to express force is Newton or
`k g m s^(2)`

`\text {Force}=m * \text {acceleration}`

b) Mass:

Mass refers feature of the physical bodies and evaluation of its resistance to the acceleration (change in the state of its movement) under the action of net force. The mass of the object also determines its gravitational attraction strength towards other objects. It is expressed in Kilograms (kg) (SI Unit) and can be mentioned in grams also.

c) Speed:

The object’s speed denotes the degree of variation in its position relative to the reference frame and as the functions of time. It is denoted by m/s (SI Unit) and other units are mph‎, ‎ft/s

`\text {velocity}=\frac{\text {distance}}{\text {time}}`

d) Acceleration:

Acceleration (a) refers the speed change with respect to time. It is expressed in
`m / s^(2)`

`\text {acceleration}=\frac{\text {distance}}{(\text {time})^(2)}=\frac{\text {velocity}}{\text {time}}`

e) Velocity means the same of the word “speed” expressed in m/s

f) time:

Time is defined as the time during which everything happens, or the exact moment at which something happens. It is expressed in seconds (s).
