What must be true about the forces in order for a car to roll down a ramp?
The force of gravity must be greater than the force of friction between the ramp and the car's wheels. This allows the car to overcome the resistance and move down the ramp.
What must be overcome in order to get a car to move?
To get a car to move, you must overcome static friction between the tires and the ground. This requires providing enough force to break this frictional force and allow the wheels to start turning. Once the wheels begin to move, the car can accelerate and maintain motion.
What forces are there when a car accelerates?
When a car accelerates, the primary forces at play are the force of friction between the tires and the road, which propels the car forward, and the force of inertia, which resists changes in motion. Additionally, the engine generates power to overcome these forces and propel the car forward.
Why is friction greatest when an object is stationary?
Friction is greatest when an object is stationary because static friction resists the initial motion of the object. At rest, the microscopic irregularities of the surfaces in contact have time to settle into each other, creating a stronger interlocking effect. This makes it harder to overcome the static friction and move the object.
What are some examples of direct forces?
Examples of direct forces include pushing a car to move it, pulling a door to open it, or kicking a ball to make it move. These forces directly act on an object to cause a change in its motion or state.

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.
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

Why are forces balanced when a car is travelling at a steady speed?
When a car is travelling at a steady speed, the driving force from the engine is equal to the total resistive forces acting against the car, such as air resistance and friction. This balance of forces allows the car to maintain a constant velocity without accelerating or decelerating.
How does balanced forces act on a car?
Balanced forces on a car occur when all external forces acting on it are equal and opposite, resulting in no change in the car's motion. This means that the car continues to move at a constant velocity or remains at rest. Balanced forces can include the force of gravity, air resistance, and the force of the engine pushing the car forward.
