In the case of the attraction force between the Earth and the moon, which of the following statements is true?
Earth has greater attraction than the moon.
Moon has greater attraction than the Earth
Earth and moon have equal force of attraction to each other.
Earth and moon have an attraction equivalent to the Sun.
The statement "An object with no unbalanced forces acting on it will naturally come to rest" is according to:
Newton's First Law of Motion
Newton's Second Law of Motion
Newton's Third Law of Motion
Nothing. It's false.
Which of the following is not a force?
Gravity and Centrifugal force.
Centripetal force and Tension force.
Friction.
Nothing. All of the above are forces.
Imagine spinning in a fast speed. In uniform circular motion, you feel being pushed outwards because of:
Centripetal Force
Centrifugal Force
Inertia
Rotational Speed
In a car collision, your body moves opposite to the collision force. This is an example of:
Newton's First Law
Newton's Third Law and Inertia
Inertia only
Velocity of the vehicle
You touched a plastic block and a metal sheet. In normal ambient temperature, you felt metal sheet is colder than the plastic block. Now, you put an ice on top of both materials. Where will ice melt faster?
Plastic block
Metal sheet
Same duration
The ice will not melt
A feather and a ball do have different mass but fall exactly the same rate in a vacuum. Which of the following statements explain the experiment?
All objects have the same force-inertia ratio.
All objects neglects mass in vacuum.
All objects possess the same kinetic energy in a vacuum.
All of the above.
After you baked a cake, you cannot touch the cake pan but can touch the cake. You precisely measured the temperature of the cake and the pan. Which of the following statements explain the experiment?
The cake and the pan is just near to each other.
The pan transfers the heat faster.
The cake do have a special ingredient.
The pan absorbs the heat from the cake.
Which of the following statement is true?
Velocity and Speed are either positive or negative value.
Velocity is neither positive nor negative value.
Speed is either positive or negative value.
None of the above.
Earth is rotating roughly 1,000 miles per hour. Why we do not feel the earth's rotation even in the poles?
Because of the gravity of the Earth.
Because of the mass attracted by the Sun.
Because of nearly constant speed.
Because of the size.
Why does the Earth does not stop in rotating?
Because of high rotational speed.
Because of inertia.
Because of Newton's third law of motion.
Because of the mass.
Which of the following describes gravity?
Gravity is an upward force.
Gravity is a downward force.
Gravity is an acceleration.
All of the above.

Speed and Acceleration
Laws of Motion
Kinematics
Relative Velocity

Direction
Position
Acceleration
