What gives an object gravity?

Physics
1 answer:
Oksana_A [137]3 years ago
8 0

We don't know WHY there are gravitational forces that attract everything
to everything else.

We DO know that the more mass is involved, the stronger the forces are,
and we know that if an object had no mass then it wouldn't be affected by
gravity.  So you could say that it's MASS that gives an object gravity, and
the more mass the object has, the more gravity it has.

Acceleration is equal to the initial velocity minus the final velocity, then divided by time.true or false
tatiyna

Almost true but not quite.

That would give you the negative of the actual acceleration.

It should be the other way around:

(final v) minus (initial v), then divide by time.

Relate a real life phenomenon with each branch of physics
anastassius [24]

Answer:

Branches of physics with real life examples

In measuring and understanding nuclear fission (a real life phenomenon), all branches of theoretical and experimental physics have to be employed. Physics branches needed in it are, radiation detection and measurement, nuclear physics, statistical physics, thermodynamics, and almost all others.

The magnitude of the net force versus time graph has a rectangular shape. Often in physics geometric properties of graphs have p
Blizzard [7]

Answer:

True

Explanation:

In this particular case, the area of the graph represents the impulse.

In fact, impulse is defined as the change in momentum of an object:

I=\Delta p

Moreover, impulse is also defined as the product between the magnitude of the force acting on an object and the duration of the collision:

I=F\Delta t

If we plot a graph of the force versus the time, if the force is constant then this graph will have a rectangular shape, and the area under the graph will simply be the product

F\cdot \Delta t

which corresponds to the definition of impulse.

The velocity of an object is positive and steadily increasing. Which of the following graphs represents how the acceleration of
stiv31 [10]
If an object's velocity is steadily increasing it means that the acceleration is constant at a certain value.

Choice A shows an acceleration of zero which would only be true if the object was not moving or if its velocity was not changing.

Choice B gives us a graph showing acceleration increasing over time and is therefore incorrect.

Choice C is correct because the acceleration is constant. Steadily increasing tells us that the acceleration is fixed at a certain value.

Choice D is incorrect an represents a constant negative acceleration. This would be the case if the object was steadily decreasing in velocity.
