The force of gravity is the
force with which massively large objects such as the earth attracts another
object towards itself. All objects of the earth exert a gravity that is
directed towards the center of the earth. Therefore, the force of gravity of
the earth is equal to the mass of the object times acceleration due to gravity.
F = ma
4.9N = m (9.8 m/s^2), note that
N (newtons) = kg-m/s^2
<u>m = 0.5 kg</u>
<u>The mass of the object is
0.5kg.</u>
Answer:
F = 339.23 N
Explanation:
Weight of a car, W = 1050 N
Initial velocity, u = 0
Final velocity, v = 42 m/s
Time, t = 13 s
The weight of an object is given by :
W = mg
g is the acceleration due to gravity

The force acting on car is :

So, the force acting on the car is 339.23 N.
According to meteoric material, the solar system was formed around <u>4.6 billion years</u> ago.
<h3>What substance makes up a meteorite?</h3>
- With just trace levels of sulphide and carbide minerals, they are primarily composed of iron-nickel metal.
- Many asteroids melted during the radioactive element decay in the early solar system, and the iron they carried, being dense, sank to the centre to create a metallic core.
<h3>What is the term for meteorite metal?</h3>
- Meteoric iron, also known as meteoritic iron, is a native metal and a protoplanetary-disk remnant from the early universe that is found in meteorites.
- It is mostly composed of the metals iron and nickel, primarily in the crystalline phases kamacite and taenite.

Water expands when it freezes (that's why you should never put closed, fully filled water bottles in the freezer !)
