Motion

What does displacement measure in physics?

• The total path traveled regardless of direction

• The total time taken to travel from start to end

• The shortest path between the start and end points

• The speed of the journey

What is the unit of acceleration?

• Kilometers per hour

• Meters per second squared

• Kilograms

• Newtons

According to Newton's first law of motion, what will happen to an object in motion if no external force acts on it?

• It will stop immediately

• It will change direction

• It will increase its speed

• It will continue moving at the same velocity

What does Newton's third law state?

• Every action has an equal and opposite reaction

• Force equals mass times acceleration

• Gravity pulls objects at 9.8 m/s squared

• Objects in motion stay in motion unless acted upon

What effect does friction have on a moving car?

• It increases the car's speed

• It has no effect

• It helps the car stop

• It changes the car's direction
