u=v+at
a=ut+v
t=u+vt
When a sailor jumps in the forward direction from a small boat the boat moves backwards. Here reaction force is
In the same direction of applied force.
Opposite to the direction of applied force

None of these
Don't Know
SI unit of force is

Forces in a Newton's third law pair have equal magnitudes but act in opposite (a) .
Newton's first law of motion is also called Galileo's law of (a) .
The rockets work on the principle of conservation of (a) .
The inertia of an object tends to cause an object
to increase its speed
to decrease its speed
to resist a change in its state of motion
to decelerate due to friction
A fielder pulls his hands backwards after catching the cricket ball. This enables the fielder to:
exert larger force on the ball
reduce the force exerted by the ball
increase the rate of change of momentum
keep the ball in hands firmly
