What are the units on both sides of the equation: x=vt+1/2at^2.
On the left side of the equation, we have the variable x, which represents the displacement or distance traveled. The unit of x is typically meters (m).
On the right side of the equation, we have the product of three terms:
- vt represents the product of velocity (v) and time (t). The unit of velocity is typically meters per second (m/s), and the unit of time is typically seconds (s). So, the product vt has units of meters (m).
- 1/2at^2 represents half of the product of acceleration (a) and time squared (t^2). The unit of acceleration is typically meters per second squared (m/s^2), and the unit of time squared is typically seconds squared (s^2). So, the product 1/2at^2 has units of meters (m).
Therefore, both sides of the equation have units of meters (m).
On both sides of the equation, we have the following units:
- Left side (x): Position or displacement (unit: meters, m)
- Right side (vt): Velocity multiplied by time (unit: meters per second, m/s * seconds, s)
- Right side (1/2at^2): Acceleration multiplied by time squared, (unit: meters per second squared, m/s^2 * seconds squared, s^2)
Therefore, the equation x = vt + 1/2at^2 has consistent units on both sides, which are meters (m).
To determine the units on both sides of the equation, let's break down the equation into its components.
The equation you provided is:
x = vt + 1/2at^2
On the left side of the equation, x represents the displacement or position, which is measured in units of length such as meters (m), feet (ft), or kilometers (km). Therefore, the units on the left side of the equation are units of length.
On the right side of the equation, the terms v, t, and a represent velocity, time, and acceleration, respectively.
Velocity (v) is measured in units of length per unit time, such as meters per second (m/s) or kilometers per hour (km/h).
Time (t) is measured in units of time, such as seconds (s), minutes (min), or hours (h).
Acceleration (a) is measured in units of length per unit time squared, such as meters per second squared (m/s^2) or feet per second squared (ft/s^2).
Now, looking at the equation as a whole, since addition and multiplication of physical quantities require them to have the same units, we can conclude that the units on both sides of the equation must be the same. Therefore, the units on both sides of the equation are units of length.
