Q1:What main estimation of the inaccuracy in physical measurements?
Q2:Choose the correct answer"The Mean Value (x) "It is:- the sum of the errors
- the Mean of the errors
- the absolute value function inequalities involving variables
Q3:An error may be defined as:
- the difference between the measured value and real value
- the real value measured
Q4:In an elastic collision:
- The total energy of the system changes
- The total energy of the system remains constant
- Rotational motion converts to linear motion.
Q5:In an inelastic collision:
- Objects retain their entire kinetic energy.
- The total energy is converted entirely into kinetic energy.
- Objects remain in a state of complete rest.
- Objects change shape and lose energy during the collision.
Q6:In an inelastic collision:
- The system conserves momentum.
- The total energy converts to internal energy.
- Objects retain their original shape.
- The total energy converts to kinetic energy.

Experiment to study the effect of gravity on the motion of
falling objects without external influences such as air or
friction. The experiment involves dropping an object from
a given height and measuring the time it takes to reach the
ground-
