Question

use the vocabulary words from
ead it\ to complete the following sentences. have you ever noticed that objects have a tendency to resist changes in motion and just continue what they are doing? this is called (4)____. all objects follow the same rule about changing motion - an object in motion stays in motion unless acted upon by an unbalanced force - or (5)__. when we talk about (6)__, or a push or a pull on an object, we tend to talk a lot about one force in particular. (7)__ is the downward pull of the earth on objects. if you study the science of movement, then you are studying the field of (8)____.

Explanation:

• For (4), the description of objects resisting changes in motion matches the definition of inertia.
• For (5), Newton's 1st Law states that an object in motion stays in motion unless acted upon by an unbalanced force.
• For (6), a push or pull on an object is defined as a force.
• For (7), the downward pull of the Earth on objects is gravity.
• For (8), the science of movement is physics.

Answer:

1. inertia
2. Newton's 1st Law
3. forces
4. gravity
5. physics
