friction

What is friction?

• Friction is the force that opposes the motion of an object when it is in contact with another object.

• Friction is the force that attracts objects to each other

• Friction is the force that causes objects to float

• Friction is the force that accelerates the motion of an object

Give an example of friction in everyday life.

• Walking on the ground

• Swimming in water

• Riding a bike on a smooth road

• Sliding on ice

What is the difference between push and pull?

• The difference between push and pull is the direction in which the force is applied: push moves away from the body, while pull moves towards the body.

• The difference between push and pull is the sound they make

• The difference between push and pull is the temperature at which they occur

• The difference between push and pull is the color of the objects involved

How does friction affect the movement of objects?

• Friction can cause objects to speed up.

• Friction can cause objects to slow down or stop.

• Friction has no effect on the movement of objects.

• Friction only affects the direction of movement of objects.

Explain how friction helps in stopping a moving object.

• Friction helps in stopping a moving object by attracting it towards the direction of motion

• Friction helps in stopping a moving object by increasing its speed

• Friction helps in stopping a moving object by reducing its weight

• Friction helps in stopping a moving object by creating a force that opposes its motion.

What are the factors that affect friction?

• Temperature of the surfaces

• Nature of surfaces, force pressing the surfaces together, and smoothness of surfaces

• Distance between the surfaces

• Color of the surfaces

Describe a situation where push is used to move an object.

• Pushing a car when it runs out of gas or breaks down.

• Pushing a shopping cart in a store

• Pushing a door open

• Pushing a button on a remote control

Explain how pull is used to move an object.

• Pulling an object involves applying force in the direction of the movement of the object, typically using a rope, chain, or handle.

• Using a magnet to move the object

• Blowing air towards the object

• Pushing an object with your hands

How can you reduce friction between two surfaces?

• Increasing the roughness of the surfaces

• Applying more pressure between the surfaces

• Adding more weight to the surfaces

• Using lubricants or smooth and polished surfaces

Why is friction important in our daily lives?

• Friction is important in our daily lives because it helps us to walk, drive, and grip objects. It also allows us to write, play sports, and stop moving objects.

• Friction is not important in our daily lives because it slows down the process of doing things

• Friction is not important in our daily lives because it causes accidents and injuries

• Friction is not important in our daily lives because it makes it difficult to move objects
