Word Bank: Balanced Force Fluid Friction Gravity Inertia Lubricants Rolling Sliding UnbalancedWrite it down in case something goes wrong with the quiz. Good luck:)

• 1.

### A ________ is a push or a pull.

Explanation
The correct answer for this question is "force". In physics, force is defined as a push or a pull that can cause an object to accelerate, decelerate, or change direction. It is a vector quantity, meaning it has both magnitude and direction. The variations in capitalization do not change the meaning of the word, as it still refers to the same concept.

### ________ is a force that acts in a direction opposite of the motion.

Explanation
Friction is a force that acts in a direction opposite to the motion. It occurs when two surfaces come into contact and resist each other's motion. Friction can be influenced by factors such as the roughness of the surfaces, the force pressing the surfaces together, and the type of materials involved. The amount of friction depends on these factors and can be increased or decreased by altering them.

• 3.

### The force exerted by a fluid (ex. air, water, oil) is called ________ friction.

Explanation
The force exerted by a fluid is called fluid friction. In this context, fluid refers to any substance that can flow, such as air, water, or oil. The variations in capitalization (fluid, fLUID, FLUID, fLuId, FlUiD) do not affect the meaning of the term.

Rate this question:

• 4.

### A property of matter which resists any motion is called ________.

Explanation
Inertia is a property of matter that resists any motion. It is the tendency of an object to resist changes in its velocity, whether that is starting, stopping, or changing direction. The correct answer is "Inertia" because it is spelled correctly and represents the property being described. The variations in capitalization do not affect the meaning of the word.

• 5.

### The force of attraction that exists between all objects in the universe is called falling friction also known as ________.

Explanation
The force of attraction that exists between all objects in the universe is called gravity. It is a fundamental force that governs the motion of celestial bodies and is responsible for keeping planets in orbit around the sun and objects on Earth's surface. Gravity is not affected by the capitalization of letters, so it can be written as gravity, gRAVITY, gRaViTy, or GrAvItY.

Rate this question:

• 6.

• 7.

### Two forces which are both acting in opposite directions are called ________ forces.

Explanation
The correct answer for this question is "balanced". The term "balanced" refers to two forces that are equal in magnitude and opposite in direction, resulting in a net force of zero. It is important to note that the capitalization of the word does not change its meaning in this context.

Rate this question:

• 8.

### When solid objects slide over each other, that type of friction is called ________ friction.

Explanation
When solid objects slide over each other, the type of friction that occurs is called sliding friction. This type of friction is caused by the resistance between the surfaces of the objects as they move against each other. It is characterized by a smooth and continuous motion between the objects.

Rate this question:

• 9.

### The friction produced by rolling objects (ex. wheels, balls) is called ________ friction.

Explanation
The friction produced by rolling objects is called rolling friction. This type of friction occurs when an object rolls over a surface, such as a wheel or a ball. Rolling friction is generally less than sliding friction, which occurs when an object slides over a surface. Rolling friction is important in various everyday activities, such as driving a car or playing sports that involve rolling objects.

Rate this question:

• 10.

### Slippery substances such as oil, wax and grease are called ________.

Explanation
Slippery substances such as oil, wax, and grease are called lubricants.
