Section A

B

:

(1)

Average Velocity = Total Shift / Total Time Considered

Total Displacement = Location under the shape of v-t graph

Q Area beneath the curve A � Location under competition B

⇒ Total shift of A � Total shift of B

⇒ Typical Velocity of any � Common Velocity of B

(2)

Average Velocity =

Final Velocity - Initial Velocity

Total Time Taken

Queen Final Speed of A = Final Velocity of N

Q Final Velocity of the = Last Velocity of B

Q Total Period Taken of A = Total Time Taken of M

⇒ Normal Acceleration of any = Speeding of W

(3)

Total Displacement sama dengan Area underneath the curve of v-t chart

Q Location under the contour A � Area beneath curve M

⇒ Total displacement of the � Total displacement of B

:

(1)

In case the vehicle prevents suddenly, by inertia, the passengers can keep go forward and may even rush for the front windows. However , with the seat belts, it will provide a backwards force preventing the traveler go forward.

(2)

Mass can be described as measure of Inertia. ***

Mass ↑ ⇒ Inertia ↑ ⇒ More difficult to stop your vehicle. (3)

Acceleration ↑ ⇒ More difficult to halt the car while using same velocity Remarks: This question can be deleted in live newspaper.

Law of Conversation of Energy:

Energy in a system cannot be created or damaged,

it could only be changed from one form to another form.

Loss of P. E. = Gain in K. At the.

⇒ Same Speed when the marble reaches the ends of the two rails, Nevertheless the direction in the velocity is definitely not the same.

(2)

θ A > θB,

By Law of conversation of one's,

u A = u B sama dengan 0,

Loss of P. E. = Gain in E. E.

v A sama dengan vB,

⇒ K. Elizabeth. is the same when it actually reaches the ends

a A = magnesium sin θ A > a N = mg sin θ B, of both rails

(3)

With a =

And so marble travel through rail A will reach the end first.

Simply by Newton's subsequent Law: N = mother
