1a.When a bus suddenly starts, the passengers sitting or standing in the bus tend to fall backward. This is due to inertia of rest and can be explained as follows: when the bus suddenly starts, the lower part of the body of the passenger which is in contact with the bus moves along with the bus while the upper part of the body tends to retain its state of rest due to inertia. As a result, the passenger falls backward.
2a.When moving bus suddenly stops, the passengers sitting or standing in the bus are thrown forward. This is due to inertia of motion and can be explained as follows: when the moving bus suddenly stops, the lower part of the body of the passenger contact with the bus suddenly comes to rest while the upper part of the body tends to retain its state of motion due to inertia. As a result, the passenger is thrown forward.
3a.When a person jumps out of a moving vehicle, he falls forward due to inertia of motion.
1b.When you kick a ball, you exert force in a specific direction, which is the direction in which it will travel.In addition, the stronger that ball is kicked, the stronger the force we put on it and the further away it will go.
2b.<span>Professional athletes move their hands back once they catch the ball as it provides the ball more time to lose its speed, and in turn apply less force on its part.
</span>3b.<span>In a golf game, the acceleration of the ball is directly proportional to the force applied to the club and inversely proportional to its mass. In the way influences the force of the air that can cause a small change in its direction.</span>
Explanation:
It is known that relation between velocity and height is as follows.
v =
where, g = acceleration due to gravity = 9.8
h = height = 0.2 m
Therefore, velocity is calculated as follows.
v =
=
= 3.92 m/s
Also,
Putting the given values into the above formula as follows.
=
=
= m/s
or, = m/s
Thus, we can conclude that recoil speed of the Earth is m/s.
As the plane falls the parabolic path remains directly below as the plane continues to fly over. This give more of an overview. When the package falls vertical acceleration happens as there is a vertical velocity as the package falls form high above. The downwards motion of gravity acts on the package if the approximated projectile motion ignoring air resistance.
Answer:
the mass deficit is directly proportional to bond reeling
Explanation:
The effect of the mass deficit in the nuclei is
δ = m_nucleons - m_nucleo
the delta quantity is the binding energy of the atomic nucleus,
This mass is related to energy by the Einstein relation
ΔE = c² Δm
therefore the mass deficit is directly proportional to bond reeling
