A 10-kg brick and a 1-kg book are dropped in a vacuum. The force of gravity on the 10-kg brick is what?

Answer 1

Force of gravity is proportionate to the mass: F = mg, where g is the constant of proportionality, also known as the gravitational constant. Since g = 9.8 m/s^2, we see that the force of gravity on the 10 kg brick is F = mg = (10 kg)*(9.8 m/s^2) = 98 kg m/s^2 = 98 N.

Answer 2

force = mass * acceleration

If you drop the brick in a vacuum at the surface of the earth,
you have:

force = 10 kg * 9.8 m/sec^2 = 98 newtons

Answer 3

Neither brick nor book can be dropped in a vacuum like in a space.
The force of gravity is zero because your question is contradicted by itself.
( Vacuum means no gravity. )

Answer 4

There is no concept of dropped in a vacuum (by itself). The vacuum, or lack of it has no real bearing on the gravity. The surrounding is what governs the gravitational force. If, you are talking about dropping them in a vacuum on earth, then the other answers here are in the right directionl.

Answer 5

The acceleration due to gravity on any object is always the same (assuming you are on the planet Earth) - 9.81 m/s², pulling down toward the ground. It makes no difference how massive the object is - it's always 9.81 m/s² downward. So, the force of gravity is the object's mass times the acceleration due to gravity. In this case, the 10kg brick is multiplied by 9.81 m/s² to get a force equal to 98.1 Newtons.

Answer 6

The simple answer is 10 kg- force.

In newtons it is 10 x 9.8 = 98 newton.

For practical purpose we can take it approximately as 100 newton.

Answer 7

The equation is: F=ma, or "tension equals mass situations acceleration". The *acceleration* of gravity is a persevering with (in the international, g, extra or less 9.8 m/s^2). The tension isn't consistent. If mass is better tenfold, tension is better tenfold besides. the respond is 'c'. (it particularly is assuming that the bricks are being dropped in the comparable place, and that gravity is latest. If the bricks are being dropped in diverse places, the respond is 'd'. If there is no gravity latest, then the tension of gravity is 0, so 'a', 'b', and 'c' are ALL best.)
