Question

imagine that youre riding in a car and the driver suddenly puts on the brakes. the car stops, but your body seems to keep going! you slide forward in your seat...until your seatbelt catches you and holds you back. youve just experienced newtons first law of motion. newtons first law of motion is this: an object at rest tends to stay at rest, and an object in motion tends to stay in motion, unless acted upon by an outside force. newtons law has two parts. the first part says that if an object is \at rest,\ or still, it will continue to be still unless something moves it. if your car is parked in the driveway, it will stay right there until someone, or something, comes along and starts it or pushes it. but what about objects that are moving? according to newtons first law, a moving object stays in motion in a straight line and at a steady speed. think about sitting in that moving car again. your body is in motion at the same speed as the car. the car has brakes to slow it down, but your body wants to stay in motion at the same, steady speed. thats why you slide forward in your seat, and thats why seatbelts are so important! outside forces, like air resistance and friction, slow things down and make them stop. sometimes a moving object bumps into another object, and the impact makes it stop or change direction. if it werent for these outside forces, then objects actually would stay in motion forever! fill in the missing words to complete the sentences about newtons first law of motion. then, copy the boxed letters on the lines below to solve the puzzle. 1. one example of an outside force that slows down moving objects is ______ ____ ____ ____ ____ ____ ____ ____. 2. newtons law says that an object in motion will stay in ____ ____ ____ ____ ____ ____. 3. newton said that a moving object will travel at a steady ____ ____ ____ ____ ____. 4. objects stay at rest or in motion until an outside ____ ____ ____ ____ ____ interferes. 5. when an object is not moving, it is at ____ ____ ____ ____. 6. a moving object will go in a ____ ____ ____ ____ ____ ____ ____ ____ line. 7. isaac newton described how objects behave with his ____ ____ ____ ____ of motion. another name for newtons first law of motion is: the law of ____ ____ ____ ____ ____ ____ ______.

Explanation:

The text explains Newton’s First Law of Motion (law of inertia), stating objects at rest stay at rest and objects in motion stay in motion unless acted on by an outside force. Examples include seatbelt use when a car brakes and outside forces like friction slowing objects.

Answer:

(Note: Since the puzzle’s boxed letters are not visible, the following are the completed sentences based on the text; the puzzle solution requires boxed letters from the original activity.)

1. One example of an outside force that slows down moving objects is air resistance (or friction).
2. Newton’s law says that an object in motion will stay in motion.
3. Newton said that a moving object will travel at a steady speed.
4. Objects stay at rest or in motion until an outside force interferes.
5. When an object is not moving, it is at rest.
6. A moving object will go in a straight line.
7. Isaac Newton described how objects behave with his laws of motion.

Another name for Newton’s First Law of Motion is: The law of inertia.
