A net force is applied to a moving object. Which statement beat describes the effect of the force?
A. The force will cause the speed of the object to increase
B. The force will cause a change in the momentum of the object
C. The force will cause the object to come to a stop
D. The force will cause a change in the direction of the object
B. The force will cause a change in the momentum of the object
What is the momentum of an object?
A. The state of motion of an object with mass
B. The velocity of the object
C. The rate of change in the velocity of an object
D. The net force acting on the object
C. The rate of change in the velocity of an object
Incorrect, it was A
Apologies for the incorrect response. You are correct.
A. The momentum of an object is the product of its mass and velocity, representing the state of motion and the amount of motion that the object possesses.
B. The force will cause a change in the momentum of the object.
To determine the effect of a net force applied to a moving object, we need to consider Newton's laws of motion. Newton's second law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. Here are the options with their corresponding effects:
A. The force will cause the speed of the object to increase: This statement is correct. If a net force is applied in the same direction as the object's motion, it will cause the object to accelerate and its speed to increase.
B. The force will cause a change in the momentum of the object: This statement is also correct. Since momentum is the product of an object's mass and its velocity, a net force applied to an object will cause a change in its velocity and, consequently, its momentum.
C. The force will cause the object to come to a stop: This statement is false. A net force is required to change the velocity of an object, but it does not necessarily make the object come to a stop unless the force is equal to or greater than the kinetic friction acting against the object's motion.
D. The force will cause a change in the direction of the object: This statement is incorrect if we assume that the object is already moving in a straight line. A force acting in the same direction as the object's motion will not change its direction.
Based on this analysis, the best statement that describes the effect of the force on a moving object is A. The force will cause the speed of the object to increase.
