Hi there!
The period is given by:
T = Period (sec)
w = angular frequency (rad/sec)
According to the equation for SHM in terms of position:
y(t) = Asin(ωt + φ)
A = Amplitude (m)
ω = angular frequency (rad/sec)
t = time (sec)
φ = phase angle
In this instance, the angular frequency is given as 18π.
Plug this value into the equation for T:
Yes, Kinetic Energy is a scalar quantity because the direction is not needed. A scalar quantity is one dimensional measurement.
Explanation:
- Kinetic Energy is a scalar quantity that means it has only a magnitude and no direction.
- Energy has a size but no direction; two objects can have the same kinetic energy but they travel in opposite directions.
- The formula of Kinetic Energy is
- K.E =
- Mass is a scalar quantity and velocity is a vector quantity.
- squaring velocity will make vector to scalar quantity.
