Question

all formulas of ch-9 force and laws of motion​

Answer 1

Explanation:

All formulas from chapter laws of motion for class 9 (PHYSICS)

speed = total distance travelled / time required.

velocity = displacement / time.

(a) acceleration = change in velocity / time. (b) acceleration = a = final velocity - initial velocity / time. ...

three equations of motion:- ...

rate of change of momentum = change in momentum / time.

Answer 2

Answer:

FORMULAS FOR FORCE AND LAWS OF MOTION:

1) Force = Mass × Acceleration

2) Force = Momentum/Time

3) Work = Force × Displacement

4) Momentum = Mass × Velocity

5) Acceleration = Velocity/Time

Now, the equations for laws of motion (i.e. kinematics)

$1) v = u + at\\2)s = ut + \frac{1}{2} at^{2} \\3)v^{2} = u^{2} + 2as$

"v" is final velocity, "u" is initial velocity, "a" is acceleration and "s" is the displacement and "t" is the time taken.

Some Additional Information:

• The displacement, acceleration, and velocity of an object are all vector quantities.

• The product of mass and velocity defines momentum as a vector quantity.

• In other words, force is the rate at which momentum changes, which is the product of mass and velocity.
