James is trying to prove newton's 2nd law of motion. he tries to move four different objects with different masses from point a to point b. the objects are a toy car, a car, a refrigerator and a kitchen table. james finds that it takes the least amount of force to move the a) a b) b c) c d) d

Hello mate!

By Newton's laws. we know that when we apply a force in an object, then we also are applying acceleration, given by the equation F =ma, where F is the applied force, m is the mass of the object and a is the acceleration.

Now in this problem, we only have that James want to move objects from point A to point B. If the problem says that James does it at the same time for each object, then we could assume that each object has the same acceleration A.  

F = m*A

then if the mass of the o

object increases, the force needed to move it at the given acceleration will increase also, then the object that requires less force is the object with less mass, in this case, the toy car.

But in this problem never says that the objects are moved with the same acceleration (or in the same amount of time), then we could apply the same force in the four objects and eventually the four will get to the point b ( for example, the refrigerator would take a lot more of time than the toy car.

the components of a vector are the parts of the vectors that are to each other.
