1. Which of the following best describes the movement of an object at rest if not outside sources act on it.
A it will move due to inertia
B)gravity will take hold
C) it will stay at rest due to inertia
D) it will stay at least due to gravity
2. A 2,500 kg car moves south at 15 m/s^2; 15 m/s^2 south is the______of the car
A) acceleration
B)displacement
C)velocity
D)speed
3. Two people are pushing a couch from opposite sides. One person is pushing to the right with a force of 3N. The other person is using to the left with a force of 4N. Which of the following best describes the movement of the couch.
A) the couch will move to the left with force of 1N
B) the couch will not move
C) the couch will move right with the force of 7N
D) the couch will movleft with the force of 7N
you need to revisit 1. and 3.

1. The correct answer is C) It will stay at rest due to inertia. Inertia is the tendency of an object to resist changes in its state of motion. If no external forces act on an object at rest, it will remain at rest due to its inertia.
2. The correct answer is C) Velocity. Velocity is a vector quantity that describes both the magnitude (speed) and direction of motion. In this case, the car moving south at 15 m/s^2 indicates its velocity.
3. The correct answer is B) The couch will not move. When two forces act in opposite directions with the same magnitude, the net force will be zero, resulting in no movement. In this case, the person pushing with 3N to the right and the person pushing with 4N to the left will create a balanced force, canceling each other out and causing the couch to remain stationary.
My answer selections are
1)A
