what happens to the acceleration when the force on an object is doubled?

• acceleration also doubles

• acceleration becomes half

• no change in the acceleration

• acceleration becomes zero

what happens to the acceleration of an object when the mass is decreased in half? (force remains the same)

• acceleration doubles

• acceleration is also halves

• acceleration increases 4 times

• acceleration becomes zero
