Which law of motion gives the measure of force? Write an expression for force
Answers
ANSWER
Newton's second law of motion
Newton's second law of motionNewton's second law of motion gives the quantitative measurement of force; F = ma.
Answer:
The law of motion that gives the measure of force is Newton's second law of motion. The expression for force is given by: F=m×a
EXPLAINATION: Force = Mass × Acceleration
or, F = m × a
where F is the force applied, m is the mass of the object, and a is the acceleration possessed by the object.
Newton's second law of motion.
Newton's second law of motion states that the acceleration of an object is proportional to the net force applied to it and inversely proportional to its mass.
Example of Newton's second law of motion - Throwing a ball: When a person throws a ball, they apply a force to it. The acceleration of the ball depends on the force applied and its mass. The greater the force and the lighter the ball, the greater the acceleration.
Acceleration
Acceleration is a measure of the rate of change in velocity of an object. It is a vector quantity and the reciprocal of acceleration is known as retardation.
