What must be overcome in order to get a car to move?
inertia
Why are forces balanced when a car is travelling at a steady speed?
If the forces weren't balanced, then the car would be (de) accelerating, thus the forces must be balanced.
Why is friction greatest when an object is stationary?
Because the frictional force must be greater than forces that would cause the object to move. Example: a car parked on a slope does not move despite the force of gravity acting to pull it down the hill. Why? Because the frictional forces are greater than the forces of gravity.
Are there forces acting on a car that is at rest xy?
There are forces acting on the car. They are just equal to the force of the car acting on the force. In example, gravity is acting on the car, but the car is pushing back equally. Therefore, the car doesn't move.
Can all forces of a car be balanced if it is moving a constant velocity?
That's exactly what we must conclude. If the forces on the car were not balanced, then its velocity would have to change.

What are the forces that act on a car when it is moving in a straight line?
Just the 3 basicsGravity to keep the car to the groundthrust to move the car forwardair resistance to move the car backwards

How does a car use force?
Rotating energy from the engine forces the drive wheels to turn, forcing the car to move.
What must be true about the forces in order for a car to roll down a ramp?
gravity
How much a children car seat must move?
It really shouldn't Move at all
Can I buy cheap car insurance in California and then move to another state and have it still apply?
No, you must change your car insurance when you move
What kind of forces does NOT change the motion of an object?
Equal and opposite forces. Imagine 2 people pushing a car, one at the front and one at the back. If they are both pushing with the same force, the car will not move.
