4. what is an unbalanced force?
5. what state is an object in when all forces are balanced?

1. what causes a car to eventually slow down and stop when you take your foot off the gas pedal?

Explanation:

1. Newton's First Law of Motion is also known as the Law of Inertia.
2. Inertia is the tendency of an object to resist changes in its state of motion.
3. Newton's First Law states that an object at rest will remain at rest, and an object in motion will remain in motion with a constant velocity, unless acted upon by an unbalanced force.
4. An unbalanced force is a force that causes a change in the motion of an object.
5. When all forces are balanced, an object is in a state of equilibrium (either at rest or moving with a constant velocity).
6. The greatest force at work on Earth is gravity.
7. - Friction: A force that opposes the relative motion of two surfaces in contact.

• Gravity: The force that attracts objects towards each other (on Earth, it pulls objects towards the center of the Earth).

1. When you take your foot off the gas pedal, a car slows down and stops due to friction (e.g., air resistance, friction in the wheels and engine).

1. Law of Inertia
