friends plz ans my question
Answers
Answer:
static Inertia, inertia of motion, impulse e impulsive force and momentum
Explanation:
a) Static inertia: Static inertia refers to the inertia of a body at rest. The inertia of a book on the table is static inertia. Dynamic inertia refers to the inertia of a body in uniform motion. The inertia of a ball moving in a frictionless floor is dynamic inertia.
b) inertia of motion: If a body is in a state of motion, then it will continue to move at the same speed in the same direction unless an external force is applied to change its state. ... On jumping, his feet touch the ground but the rest of the body still tends to remain in motion.
c) impulse e impulsive force: Impulse of a force is the time integral of a force. Impulsive forces, on the other hand, are great forces acting on a body for a short period of time. It is defined as the rate of change of momentum of a body during the time of the application of the force.
d) momentum: Momentum, product of the mass of a particle and its velocity. Momentum is a vector quantity; i.e., it has both magnitude and direction. Isaac Newton's second law of motion states that the time rate of change of momentum is equal to the force acting on the particle. See Newton's laws of motion.
Ik it's big... but thank me later.. hehehe..
