Question

Force = mass x acceleration : __________.a. for any force, there is an equal and opposite reaction force. b. the orbit of each planet about the Sun is an ellipse with the Sun at one focus. c. a planet moves faster in the part of its orbit nearer the Sun and slower when farther from the Sun, sweeping out equal areas in equal times. d. an object moves at constant velocity if there is no net force acting upon it. e. more distant planets orbit the Sun at slower average speeds, obeying the precise mathematical relationship p2 =a3.

Answer 1

Answer:

a. for any force, there is an equal and opposite reaction force.

Explanation:

Newton third law of motion states that " for every action, there is an equal and opposite reaction.

Action force= reaction force =

M₁ * a₁ = M₂ * a₂

where M₁ = mass of object 1

          a₁ = acceleration due to object 1

          M₂ = mass of object 2

          a₂ = corresponding acceleration due to object 2

this happen in everyday life of an individual. an example is seen in a groups of three man exerting a push force on a static car, the push force on the car make the car to exhibit some motion equivalent to the force applied by the three man.
