Understanding Newton's First Law of Motion

The video explains Newton's First Law of Motion, focusing on the concept of inertia. It describes how inertia affects objects at rest and in motion, using examples like a bag on a bike and a person on a bus. The video illustrates how inertia causes objects to resist changes in their state of motion unless acted upon by an external force.

What is the main concept defined by Newton's First Law of Motion?

• Acceleration

• Inertia

• Gravity

• Momentum

What is the tendency of a body to remain in its current state called?

• Velocity

• Momentum

• Inertia

• Friction

Why does a bag fall when brakes are applied suddenly?

• Due to gravity

• Due to inertia of motion

• Due to friction

• Due to air resistance

What happens to a stationary object when a force is suddenly applied?

• It moves due to gravity

• It moves due to inertia of motion

• It moves due to inertia of rest

• It remains stationary

When a bike accelerates suddenly, why does a bag on it fall?

• Due to inertia of rest

• Due to inertia of motion

• Due to gravity

• Due to air resistance

Why does a person fall backwards when a bus starts moving suddenly?

• Because of the bus's acceleration

• Because of inertia of rest in the upper body

• Because of the bus's deceleration

• Because the bus is moving too fast

What part of the body tends to remain at rest when a bus starts moving?

• Lower part

• Feet

• Upper part

• Hands
