Speed is defined as distance over time. So, since it traveled 100m in 25 sec, the speed was 100 / 25 = 4 m/s.
Answer:
true
Explanation:
Newton is the measure of the force with turns to be gravity multiplying the mass. Thus, the forces acts on the particles in the direction of the movement of the particles
Mass (kg) = force (N) / acceleration (m/s).
200/2.5 = 80
The essay will highlight the fact that for every simple machine, there is always friction involved. As per the law of conservation of energy, the energy input to a system is equivalent to the energy output. Some of this output is in the form of friction, which is not useful. As the moving parts in a machine increase, it becomes more complex and more friction is generated between its parts. Therefore, a complex machine ends up being less efficient.
