1. When a spring is pulled, the _____ is proportional to the ______ ( called ____ law.
2.Weight is the force of ____ on an object due to the pull of the _____
3. Weights and other forces are measured in ______
4. Here on Earth, the pull of gravity on a mass of 1 kg is ______ Newtons
5. Weight is measured by a _____ balance and _______ from place to place
6. Newton's first law says: every mass stays at _______ or moves at constant _______ in a _______ line unless a resultant _______ acts on it
7. To move in a _______ orbit, an object must have a _______ force on it

Answer 1

In physics, there are various concepts related to forces and motion. Hooke's law explains the relationship between force and extension in a spring. Weight is the force of gravity on an object, and it can be measured in newtons using a spring balance. Newton's first law states that an object stays at rest or moves at a constant velocity unless acted upon by a force.

Step-by-step explanation:

Filling in the Blanks:

1. When a spring is pulled, the force is proportional to the extension (called Hooke's law).
2. Weight is the force of gravity on an object due to the pull of the Earth.
3. Weights and other forces are measured in newtons.
4. Here on Earth, the pull of gravity on a mass of 1 kg is 9.8 Newtons.
5. Weight is measured by a spring balance and varies from place to place.
6. Newton's first law says: every mass stays at rest or moves at constant velocity in a straight line unless a resultant force acts on it.
7. To move in a stable orbit, an object must have a centripetal force on it.
