Answer:
The gravitational force is related to the mass of each object.
The gravitational force is an attractive force.
Explanation:
Gravitational force is a long range force of attraction between any two masses.
Mathematically given as :
where:
are the masses
r= distance between the center of mass of the two objects.
G= gravitational constant = 
From the above relation of eq. (1) it is clear that,
Gravitational force is inversely proportional to the square of the distance and directly proportional to the masses.
The mass of an object is independent of its size due to the fact that density may vary for different objects.
The force of gravity varies with height as:
where:
gravity at height 
of the center of mass of the object from the center of mass of the earth.
and we know that force:
where: m= mass of the object.
Answer:
0.5 mph in the opposite direction
Explanation:
= Mass of Cadillac = 1000 kg
= Velocity of Cadillac = 1 mph
= Mass of Volkswagen = 2000 kg
= Velocity of Volkswagen
In order to know the speed the system must have the momentum exchange
As the linear momentum of the system is conserved
The speed of the impact is given by 0.5 mph in the opposite direction
Answer:
the glass contains air bubbles that expands and contracts as the glass is heated or froze. when they expand they may cause the glass to break or even explode
Answer:
a. 9.8 m/s2.
Explanation:
The acceleration depends on the force of gravity. It's independent of the velocity of the ball.
