The two forces are the forward push produced by the car that crashes on the car that is crashed and the other is the backward force produced by the crashed car on the car that crashes. This proves the law of conservation of momentum.energy here is actually not lost or gained, it remains the same.

Describe two effects of a force on a moving object?
slow the object down or speed it up
Explain the term balanced force and unbalanced force?
balanced forces are when the two opposite forces are equal and cause no change to the object e.g a car at a steady speed. unbalanced forces would cause the car to increase or decrease in speed
What is A force that acts on rock?
Acid rain___No, rain isn't a force in and of itself, even if it is acidic. A force by definition must be able to make an object accelerate. Gravity is a force. Magnetism is also a force that might act upon a rock, depending on its elemental makeup. Friction is a force that might slow the effects of the other two (a negative acceleration).
What forces are acting on a still car and a car that is slowing down?
There are more than two forces acting on a moving car. The force of gravity keeps the car on the ground, and the normal force from the ground keeps the car from falling to the center of the earth. When the engine is running, it creates a torque which is transferred to the car's tires. Due to small and large cracks and crevices in the road and tires the two surfaces keep getting stuck together. The force must go somewhere, so the car is now applying a force on the road in the direction the wheels are rotating. Newton's 3rd law states that, "For every action, there is an equal and opposite reaction," therefore the road also applies a force to the car. This force is called a frictional force. It is static friction if the car is moving, and the tires are not sliding; it is kinetic friction if the car is moving, but the tires are sliding. This frictional force is what propels the car and is greater as static friction. The last force acting on a moving car is the drag force or air resistance and it is caused by particles of air running into the car, slowing it down.
Can friction exist without gravity?
Yes, friction exists whenever two objects touch. Friction is caused by two effects: direct contact of mechanical surface irregularities and the electromagnetic force. It has nothing at all to do with the gravitational force, the strong force, or the weak force.
The effects of the electromagnetic force on two charged particles is that of?
The effects of the electromagnetic force on two charged particles is that of repulsion between the like charges.
Two central concerns to race car designers?
Down force and lateral force.
Which the two vehicle needs a greater force to stop a car or a bus?
a sports car and a bus are both traveling at 30 km/h. which of the two will require more force to stop?why?
How does the size of the force exerted by earth gravity on a car compare with the size of force the car exert on earth?
A gravitational force exists between every two mass objects.The force is the same on both objects.
How does the size of the force exerted by earth's gravity on a car compare with the size of the force the car exert on earth?
A gravitational force exists between every two mass objects.The force is the same on both objects.

A gravitational force exists between every two mass objects.The force is the same on both objects.
Compare How does the size of the force exerted by Earths gravity on a car compare with the size of the force the car exerts on Earth?

Concept of equilibrium with the laws of motion?
An object is said to be in equilibrium when two opposing forces acting upon it create a resultant force of 0.Example:A car is sitting on a road. The force of gravity pushes the car downward, while an opposing force pushes it upward. This causes an equilibrium, and therefore the car does not move as a result of these two opposing forces.
Two identical cars have forces applied to them Car A has a 1000 N force applied Car B has a 500 N force applied Which car will have more acceleration?
well if both the car are identical in mass the acceleration is directly proportional to force and inversely proportional to mass since mass is same hence car having force of 1000 N will have more acceleration than 500 N one.
Two students together exert a force of 825 N in pushing a car for 35 m. How much work do they do on the car?
Work can be defined as force multiplies by distance for a constant force: W = F*d In this case: W = (825 N) * (35 m) = 28875 Joules
Does two foot braking increase the amount of force applied to the brakes?
It takes more effort to stop a car that does not have power brakes, although its rare to see a car without power brakes any longer. In either case, the literal answer to your question is yes it does increase the force applied to the brakes. Two feet are stronger than one. More force on the pedal translates to more force on the brake pads.
