When a moving bus is suddenly stopped, the passengers tend to fall forward. This is because of

• Inertia of rest

• Friction

• Inertia of motion

• Weight

• Gravity

• Inertia

• Friction

• Force

• Gravity

• No force

• Balanced force

• Unbalanced force

What can a force do

• Start a motion

• Stop a motion

• Change direction

• All the above

What is Newton's First Law

• F=ma
• Every action has an equal and opposite reaction
• An object at rest stays at rest, an object in motion stays in motion. 
• Friction
