Forces and Motion Concepts

The video tutorial covers key vocabulary related to forces, including pull, push, bounce, gravity, friction, and surface. It explains each term with examples, such as a horse pulling a cart, a ball bouncing, and the effects of gravity on planets. The tutorial also discusses friction between objects and defines the concept of a surface.

What does it mean to pull an object?

• To push it down

• To lift it up

• To move it towards you

• To move it away from you

Which of the following is an example of pushing?

• Pulling a cart

• Closing a door away from you

• Opening a door towards you

• Lifting a box

What happens when a ball bounces?

• It stops immediately

• It stays on the ground

• It moves up or away after hitting a surface

• It rolls continuously

Which sport involves a lot of bouncing?

• Cycling

• Swimming

• Soccer

• Basketball

What is gravity?

• A force that pushes objects away

• A force that pulls objects towards the ground

• A force that makes objects float

• A force that stops objects from moving

Why don't we fly off into space?

• Because of friction

• Because of gravity

• Because of bounce

• Because of surface tension

What is friction?

• A force that stops objects from touching

• A force that makes objects bounce

• A force between two objects moving over each other

• A force that pulls objects towards the ground

When does friction occur?

• When objects are in the air

• When objects are stationary

• When objects are touching and moving over each other

• When objects are not touching

What is the surface of an object?

• The side of something

• The inside of something

• The top part of something

• The bottom part of something

Which of the following is an example of a surface?

• The bottom of a cup

• The surface of the ocean

• The side of a building
