What is inertia?
The tendency of an object to resist any change in its state of motion
The question asks for the correct meaning of inertia.
Inertia is the property of matter described by Newton's first law of motion, which is often itself called the law of inertia.
It is the natural tendency of a body to resist any change in its state of rest or of uniform motion in a straight line.
Because of inertia, a body at rest stays at rest and a body in motion keeps moving with the same speed and direction unless an external unbalanced force acts on it.
The mass of a body is the measure of its inertia: the greater the mass, the greater the resistance to a change in its motion.
The option describing the ability to change velocity is the opposite of inertia, the engine's push is a force, and the pull towards Earth is gravity, so none of these describe inertia.
Hence the correct answer is The tendency of an object to resist any change in its state of motion.

In a desert, a beetle's motion sends fast longitudinal pulses, vL = 150 ms-1, and slower transverse pulses, vS = 50 ms-1, along the sand's surface. The sand scorpion has eight legs; spread roughly in a circle of 5 cm diameter, intercepts the faster longitudinal pulses 4.0 ms earlier than the slower transverse pulse. The pray is located at a distance of:
