The magnitude of external force acting on an object is equal to product of……
(mass and velocity, mass and acceleration, velocity and time)

Power is vector product of force and velocity.

Explain - product of mass and velocity is important in producing effect of force.

The magnitude of acceleration of centre of mass of the system is

What is not effected by the force acting on a body? (shape, velocity, mass, acceleration)

If the total external forces on the system of particle is zero, then find the velocity and acceleration of its centre of mass.

If the final velocity of an object is less than the initial velocity, then it performs accelerated motion.

A particle moves in such a way that its position vector at any time t is vec(r)=that(i)+1/2 t^(2)hat(j)+that(k) . Find as a function of time: (i) The velocity ((dvec(r))/(dt)) (ii) The speed (|(dvec(r))/(dt)|) (iii) The acceleration ((dvec(v))/(dt)) (iv) The magnitude of the acceleration (v) The magnitude of the component of acceleration along velocity (called tangential acceleration) (v) The magnitude of the component of acceleration perpendicular to velocity (called normal acceleration).

When force is applied to an object, there is no effect on its ........(mass, shape, velocity)
