A constant force is applied to an object, causing the object to accelerate at 10 m/s2.
1. What will the acceleration be if the force is halved?
2. What will the acceleration be if the object's mass is halved?
3. What will the acceleration be if the force and the object's mass are both halved?
4. What will the acceleration be if the force is halved and the object's mass is doubled?
