    Because earth is too heavy

    1Thank You

    Abhijeet Kumar 5 years, 10 months ago

    Earth is very heavy as compared to the moon. So Our Earth has more mass than moon. And we know from Newton's universal law of gravitation that product of masses of two bodies is directly proportional to the force of gravitation. So more the mass,more the gravitational force will be. So Earth has more gravitational force than moon.

    2Thank You

    Tanish Jassal 5 years, 10 months ago

    Because of the mass and weight of the earth in simple words earth have more weight so they have more gravity and moon dont have atmosphere

    Lysosomes are called suicide bags because they contain very powerful digestive enzymes which help in the removal of waste and damaged material from the cell.. When any damaged material is found inside the cell, Lysosomes secrete those powerful digestive enzymes which in turn remove the wastage by dissolving its own cell. This is the reason why Lysosomes are called suicide bags..

    Work os done when force is applied

    Om Sri Sai Ram 5 years, 10 months ago

    A work is done when force produces a motion

    0Thank You

    Sia ? 5 years, 10 months ago

    A work is done when something is moved through a distance or when a moving object is brought to rest or when it changes the direction of motion.
    When a force causes a body to move, work is being done on the object by the force. Work is the measure of energy transfer when a force (F) moves an object through a distance (d). So when work is done, energy has been transferred from one energy store to another, and so: energy transferred = work done.
