  • What is force of gravity in physics?

    Gravity, also called gravitation, is a force that exists among all material objects in the universe. For any two objects or particles having nonzero mass, the force of gravity tends to attract them toward each other.

Which is the best definition of reaction time? Reaction-time definition Reaction time is the amount of time it takes to respond to a stimulus. An example of reaction […]

  • What is perfectly elastic vs elastic?

    In physics, an elastic collision is an encounter (collision) between two bodies in which the total kinetic energy of the two bodies remains the same. In an ideal, perfectly elastic collision, there is no net conversion of kinetic energy into other forms such as heat, noise, or potential energy. What is meant by a perfectly […]

  • What is the function of a nose cone?

    The nose cone and fins of a rocket are designed to minimise drag (air resistance) and to provide stability and control (keep it pointing in the right direction without wobbling).
