Why does an object slow down when going uphill Please explain properly

Physics
1 answer:
Evgen [1.6K]4 years ago
6 0

Answer:

The change in speed on slopes is due to gravity. When going downhill, objects will accelerate (go faster), and when going uphill they will decelerate (slow down). On a flat surface, assuming that there is little friction, they will then maintain a constant speed.

A 1.0-kg block and a 2.0-kg block are pressed together on a horizontal frictionless surface with a compressed very light spring
Lunna [17]

Answer:

statement B is true

Explanation:

since same force is applied by the compressed spring on both masses so their rate of change of momenta must be same and since the lighter block has lesser mass so it must have greater velocity to have an equal change in momentum as of heavier mass.

By relation: KE=\frac{(mv)^{2} }{2m}

KE lighter=\frac{(mv)^{2} }{2(1)} , KEheavier=\frac{(mv)^{2} }{2(2)}

comparing momenta of above two equations we get

KElighter (2) = KEheavier (4)

KElighter = 2 KEheavier

Why does a plane move even when the wind is pushing against it?
boyakko [2]
A plane has more mass in it. Also, the engine is very strong which it makes the plane able to push through the wind. When the wind is pushing, it goes by it because of the engine.
