Question

factors that affect kinetic energy quick check
which characteristic will be affected by increasing the speed of an object from 30 meters per
second (\\(\frac{m}{s}\\)) to 40 meters per second(\\(\frac{m}{s}\\))? (1 point)
o weight
gravitational attraction
o kinetic energy
o mass

Explanation:

Kinetic energy formula is \(KE=\frac{1}{2}mv^{2}\), where \(m\) is mass and \(v\) is speed. Weight \(W = mg\) ( \(g\) is gravitational acceleration), gravitational attraction depends on masses and distance (\(F = G\frac{m_1m_2}{r^{2}}\)), mass is an intrinsic property. When speed \(v\) changes (from \(30\frac{m}{s}\) to \(40\frac{m}{s}\)), using \(KE=\frac{1}{2}mv^{2}\), kinetic energy changes as it is directly related to the square of speed.

Answer:

kinetic energy
