• 1.

### Gravity is exerted on all objects on our planet?

• A.

True

• B.

False

A. True
Explanation
Gravity is a fundamental force that exists between all objects with mass. It is a natural phenomenon that causes objects to be attracted towards each other. On our planet, gravity is present and exerts its force on all objects, regardless of their size or mass. This is why objects fall towards the ground when dropped and why we feel our weight. Thus, the statement "Gravity is exerted on all objects on our planet" is true.

### The moon has less amounts of gravity than the earth does?

• A.

True

• B.

False

A. True
Explanation
The moon has less gravity than the Earth because it is much smaller and less massive. Gravity is determined by the mass of an object, so the smaller mass of the moon results in weaker gravitational pull compared to the Earth. This is why objects and people weigh less on the moon than they do on Earth.

### Suppose the gravitational force is 10 N between two objects. If the distance between the masses is cut in half, what is the new force between the objects?

• A.

10 N

• B.

20 N

• C.

40 N

• D.

30 N

C. 40 N
Explanation
When the distance between the masses is cut in half, the gravitational force between the objects increases by a factor of four. This is because the gravitational force is inversely proportional to the square of the distance between the masses. Therefore, if the distance is halved, the force becomes four times stronger. In this case, since the initial force is 10 N, the new force would be 10 N multiplied by four, which is 40 N.

### Velocity Equation - V = (__) x t

g
Explanation
The correct answer is g. The equation V = g x t represents the velocity (V) of an object when it is in free fall near the surface of the Earth. In this equation, g represents the acceleration due to gravity, which is approximately 9.8 m/s^2. By multiplying g by the time (t) that the object has been falling, we can calculate its velocity.
