PHYSICS - Forces - Forces That Cause Change

The video explores the concept of force, defined as a push or pull in a specific direction, and its effects on objects. It explains how force can change an object's shape, speed, and direction, affecting its velocity. The video delves into deformation, distinguishing between elastic and plastic deformation, and discusses the elastic limit, yield point, and rupture point. A practical example using a trampoline illustrates these concepts, emphasizing safety considerations.

What is a force primarily described as?

• A push or pull in a specific direction

• A type of energy

• A change in temperature

• A form of light

Which of the following is NOT an effect of force on an object?

• Changing the direction of an object

• Changing the speed of an object

• Changing the shape of an object

• Changing the color of an object

What happens during elastic deformation?

• The object returns to its original shape

• The object changes color

• The object breaks immediately

• The object becomes heavier

What is the term for when an object does not return to its original shape after a force is removed?

• Magnetic attraction

• Thermal expansion

• Plastic deformation

• Elastic deformation

What is the rupture point in the context of deformation?

• The point where an object changes color

• The point where an object becomes magnetic

• The point where an object breaks

• The point where an object returns to its original shape
