What is needed for a change in motion to occur?
A
Vacuum
B
Force
C
Tangent Line
D
Model
Explanation: 

Detailed explanation-1: -The motion of an object is determined by the sum of the forces acting on it; if the total force on the object is not zero, its motion will change. The greater the mass of the object, the greater the force needed to achieve the same change in motion. For any given object, a larger force causes a larger change in motion.

Detailed explanation-2: -Nothing moves until a force acts upon it. If something is moving, it will carry on moving at the same speed and in the same direction until a force happens to change it. LAW 2 – Forces make things speed up (or accelerate).

Detailed explanation-3: -The speed and direction of motion can be changed by applying force on an object and thus a force can bring a change in the state of motion of an object.
