Answer:the rate of change in velocity
Explanation: acceleration =the change in velocity / time taken the unit is m/s2
While velocity is the distance traveled in a given direction/time taken.the unit is m/s
Answer:
The forms of energy involved are
1. Kinetic energy
2. Potential energy
Explanation:
The system consists of a ball initially at rest. The ball is pulled down from its equilibrium position (this builds up its potential energy) and then released. The released ball oscillates due to a continuous transition between kinetic and potential energy.
Answer:
720 J
Explanation:
The gravitational potential energy that Essam loses for every metre is given by:
where
m=72 kg is Essam's mass
is the gravitational field strength
is the difference in height
By substituting the numbers into the formula, we find
Surveys are considered the most reliable way to gather data
The answer is C.
An object on the moon is six times lighter than on Earth.
