Prokaryotic cells are the cells whose nucleus is not well defined and is called nucleoid . Eukaryotic cells are the cells whose nucleus is well defined and surrounded with a nuclear membrane . Prokaryotic cells are generally small in size and eukaryotes are generally large in size , prokaryotes - only one chromosome and eukaryotes - more than one chromosome

Show that for a freely falling body, sum of its potential and kinetic energy remained unchanged at all points during its fall

Posted by Kavita Rajput 5 years, 6 months ago

CBSE > Class 09 > Science

1 answers

Meghna Thapar 5 years, 2 months ago

As the potential energy of the freely falling object decreases, its kinetic energy increases on account of an increase in its velocity. The sum total of the potential energy and the kinetic energy of the object during its free fall remains the same, i.e., the total mechanical energy (potential energy + kinetic energy) remains constant. Thus, the law of conservation of energy is not violated.

Any object remains in the state of rest or in uniform motion along a straight line, until it is compelled to change the state by applying external force.

Explanation: If any object is in the state of rest, then it will remain in rest untill a exernal force is applied to change its state. Similarly an object will remain in motion untill any exeternal force is applied over it to change its state. This means all objects resist to in changing their state. The state of any object can be changed by applying external forces only.

If body is in rest or in motion it continued in motion or rest unless an external force applied.

case of uniform acceleration, there are three equations of motion which are also known as the laws of constant acceleration. Hence, these equations are used to derive the components like displacement(s), velocity (initial and final), time(t) and acceleration(a). ... The three equations are, v = u + at.

Aditi Kumari 5 years, 6 months ago

Distance - the total measurement of an object to be covered in a motion is called distance however displacement- the shortest distance of an object from intial to final point is called displacement ??

Amandeep Singh 5 years, 6 months ago

The distance traveled by the object between two positions gives complete information about the type of the path followed by the object. However, displacement of the object does not give proper information about the type of path followed by the object. Distance=Speed x Time whereas Displacement=Velocity x Time.

Aryan Kothari 5 years, 6 months ago

Differences Displacement is vector quantity while distance is scaler quantity. Displacement can be zero but distance cannot be zero. Similarities They both have same units - 'm'
