Which one is not an example of Newton's first law?

• A stationary car starting to move without being pushed by a force

• A fly being hit by a fly swatter

• An asteroid crashing into a planet

• A chair that isn't moving is picked up and thrown across the room

Which of these is a single-word description of Newton's first law?

• Inertia

• Force

• Velocity

• Mass

Newton's first law states that an object at rest will remain at rest unless acted upon by...

• an unbalanced force

• a force

• a constant velocity

• a cheesecake

When a car is driving along a 20km/h road and turns a corner, has its velocity changed?

• Yes, it changed direction

• Yes, it changed speed

• Yes, it changed both speed and direction

• No, it didn't change velocity

If the net force acting on a moving object is in the direction that the object moving, the object will

• stop

• speed up

• change direction

• none of the above
