If you want to find out and gauge your knowledge in Science specifically forces, then this is the quiz for you. Pushes, pull, gravitational among other natural forces are tested. Even if it is just for practice or leisure, dive in and find out.

• 1.

### A force is a push or a pull and they cannot br seen.

• A.

True

• B.

False

A. True
Explanation
This statement is true because a force is a concept in physics that describes the interaction between two objects, where one object exerts a push or pull on the other. Forces are not visible to the naked eye but their effects can be observed through the motion or deformation of objects. Therefore, forces cannot be seen directly but their presence and effects can be observed and measured.

### One of these is a type of force.

• A.

Juice

• B.

Magnetic

• C.

Light

B. Magnetic
Explanation
Magnetic force is a type of force that is exerted by magnets or magnetic fields. It is a fundamental force in nature that acts on objects with magnetic properties, such as iron or other magnetic materials. This force can attract or repel objects, depending on their magnetic properties and orientation. Juice and light, on the other hand, are not types of forces but rather forms of energy or substances. Therefore, the correct answer is magnetic.

### List the parts of bicycle

• A.

A.friction is essential

• B.

B.friction must be reduced

A. A.friction is essential
Explanation
The given correct answer states that friction is essential in a bicycle. This means that friction plays a crucial role in the functioning of a bicycle. Friction is necessary in various parts of a bicycle such as the brakes, tires, and chain. Without friction, the brakes would not be able to stop the bicycle, the tires would not grip the road, and the chain would not be able to transfer power to the wheels. Therefore, friction is essential for the proper operation and control of a bicycle.

Rate this question:

• 4.

### Friction acts between two surfaces and can be reduced using a __________. Air _________ or drag is a frictional force that acts against moving objects like cars. The more _______ an object, the lower its air resistance.

lubricant
drag
streamlined
Explanation
Friction is a force that opposes the motion between two surfaces. It can be reduced by using a lubricant, which creates a thin layer between the surfaces, reducing the contact and thus the friction. Air drag or drag is a type of frictional force that acts against moving objects, such as cars. The more streamlined an object is, the lower its air resistance, meaning it experiences less drag. Streamlining involves shaping the object in a way that allows the air to flow smoothly around it, reducing the drag force.

### Tick the correct box: A force is a push or a pull. A force is a thrust A force is  something that needs to be reduced.

• A.

A force is a push or a pull

• B.

A force is a thrust

• C.

A force is something that needs to be reduced

A. A force is a push or a pull
Explanation
The correct answer is "a force is a push or a pull" because a force is a physical interaction that can cause an object to move, change its speed, or change its direction. Pushing and pulling are common examples of forces that can be exerted on an object to make it move or change its position.
