``An unbalanced force acting on an object will cause the object to accelerate in the direction of the force''. This is known as

• newton's first law

• newton's second law

• newton's third law

• kepler's law

Newton's second law of motion states that the rates of change of momentum with respect to time is

• force

• energy

• power

• work

The accurate formulation of the laws of motion, as well as of gravitational was made by

• galelio

• kepler

• varignon

• newton

The law which describes the motion of stars, planes and comets.

• law of universal gravitation

• newton's law of motions

• kepler's law

• big bang and black hole theory

Which of the following does not describe the object as observed from earth?

• apogee

• perigee

• eccentricity

• focus

If an external pressure is applied in a confined fluid, the pressure will be increased at every point in the fluid by the amount of external pressure. This is known as

• archimedes principle

• pascal's law

• boyle's law

• bernoullis theorem

According to this law: ``The force between two charges varies directly as the magnitude of each charge and inversely as the square of the distance between them''.

• law of universal gravitation

• coulomb's law

• newton's law

• inverse-square law

``At any two points along a streamline in an ideal fluid in a steady flow, the sum of the pressure, the potential energy per unit volume and the kinetic energy per unit volume has the same value''. This concept is known as

• pascal's theorem

• bernoullis theorem

• hydraulic theorem

• ideal fluid theorem

``Whenever a net force acts on a body, it produces an acceleration in the direction of the resultant force, an acceleration that is directly proportional to the mass of the body. This theory is popularly known as

• feraday's law of forces

• newton's second law of motion

• newton's first law of motion

• hooke's law of equilibrium

A measure of the resistance of a body it offers to any changes in its angular velocity, determined by its mass and distribution of its mass about the axis of rotation is known as the

• moment of inertia

• friction

• torsion

• angular acceleration
