Linear Momentum Question: Force Exerted in Two-Body Interactions

In summary, when two cars of equal mass are approaching each other, the car that is moving exerts a larger force on the stationary car. When a truck is towing a car and accelerating, both exert equal force on each other according to Newton's Third Law. Therefore, the answers to both questions are the same.

Hello.
I need confirmation on simple linear momentum questions...

1. two cars on the surface. car A approaches to car B at Va while car B is at rest. masses of both cars are same. which car puts more force or is it same?
Car A exerts larger force on B
Car B exerts larger force on A
Same

2. truck is towing the car. when the truck is accelerating, does...
the car exerts larger force on truck
the truck exerts larger force on car
same

just these 2 questions...if you can help me out. thank you.

Newtons laws say?
 
  • #3
equan and opposite force according to third law...
so both questions's answers are same right?

No need to think about momentum. Think Newton and his 3rd law.

k thank you.
same force exerted for both questions. :biggrin:
just needed confirmation...
 

FAQ: Linear Momentum Question: Force Exerted in Two-Body Interactions

1.

What is linear momentum?

Linear momentum is a physical quantity that describes the motion of an object in a straight line. It is defined as the product of an object's mass and its velocity.

2.

How is linear momentum calculated?

Linear momentum is calculated by multiplying an object's mass (m) by its velocity (v), represented by the equation p = mv. In SI units, the unit for linear momentum is kg*m/s.

3.

What is the principle of conservation of linear momentum?

The principle of conservation of linear momentum states that in a closed system, the total linear momentum before an event is equal to the total linear momentum after the event. This means that the total momentum of all objects in a system remains constant, unless an external force acts on the system.

4.

How is linear momentum related to Newton's Laws of Motion?

Linear momentum is related to Newton's Laws of Motion through the second law, which states that the net force acting on an object is equal to the rate of change of its momentum. This means that the greater the force acting on an object, the faster its momentum will change.

5.

What are some real-world applications of linear momentum?

Some real-world applications of linear momentum include understanding the motion of objects in sports, predicting the trajectory of projectiles, and designing vehicle safety features. It is also a crucial concept in the field of rocketry and space exploration.
