One Newton is expressed in ?

Answers

Answer 1
Answer:

Answer:

It is the SI unit of force.

Explanation:

The rate of change of momentum in the body is directly proportional to the force applied on the body. It is the second law of motion.

The mathematical form of Newton's second law is

F = m x a

where, m is the mass and a be the acceleration.

If a body of mass 1 kilogram having an acceleration of 1 m/s^2, it means the force applied on the body is 1 newton.
Answer 2
Answer: The newton is the SI unit for force; it is equal to the amount of net force required to accelerate a mass of one kilogram at a rate of one meter per second squared.

Whenever the motion of an object change,____ has been applied.

Answers

Whenever the motion (speed or direction) of an object changes, we say that acceleration has occurred.  From Newton's First Law of Motion, we know that force has been applied to the object.

How can a high school student have more momentum than a truck

Answers

Answer:

When truck is at rest while student is under motion

Explanation:

Since it is obvious that the mass of a truck is more than that of a student, we know that momentum is a product of mass and velocity

P=mv where m represent mass, v is velocity. When the student has more speed than that of truck, he exerts more momentum. The only way a student can exert more momentum is by having more speed while the truck is at rest. In such case, the momentum of truck will be zero while momentum of student will have a value
