the friction of the car with the ground.
centripetal force
acts towards the Centre
the velocity and acceleration is not constant
4 of 14
resultant force
a single force that has the same effect as two or more forces.

newton's first law
An object at motion will continue; and an object at rest will stay in rest until -an external resultant force acts upon it
If an object is moving at a constant speed then there is no resultant force.
6 of 14
newtons second law
F= ma
the greater the mass of a body, the smaller the acceleration given by the particular force.
7 of 14
mass
property of an object that resists change in motion
8 of 14
newton
the force required to give a body of mass-1kg an acceleration of 1m/s2

impulse
I=FxT

principle of conversion of momentum
when two or more objects act on each other, their total momentum remains constant provided no external forces are acting.

parachute concept
When it falls; the speed starts to increase. The air resistance continues to act on it until it balances the weight. following newtons first law, it continues to be in motion at a constant velocity.
The velocity never decreases since leaving from the star
