Q: AN OBJECT IS MOVING PAST YOU IN A STRAIGHT LINE WITH A CONSTANT SPEED. YOU CAN CONCUDED
A. THAT THERE IS A CONSTANT FORCE IN THE DIRECTION OF MOTION
B. THAT THERE ARE NO FORCES ACTING ON THE OBJECT
C. THAT THE NET FORCE ON THE OBJECT IS ZERO
D. NONE OF THE ABOVE
Q#2
IF YOU DOUBLE THE FORCE APPLIED TO AN OBJECT, THE ACCEERATION
A. STAYS THE SAME
B. DOUBLES
C. CUTS IN HALF
1. Newton’s 1 law states that if the net force (the vector sum of all forces acting on an object) is zero, then the velocity of the object is constant.
Ans. B (and C
2. Newton’s 2 law F =ma
Ans. B
To answer the first question, you can use Newton's first law of motion which states that an object at rest or in uniform motion will continue that state unless acted upon by an external force. In this case, the object is moving past you in a straight line with a constant speed, which means there is no change in motion. Therefore, the correct answer would be B. That there are no forces acting on the object.
For the second question, you can use Newton's second law of motion which relates force, mass, and acceleration. The equation is F = ma, where F is the force, m is the mass of the object, and a is the acceleration. If you double the force applied to an object, according to the equation, the acceleration would also double. So, the correct answer would be B. Doubles.
