Check the correct statements about acceleration.

• If the mass is constant, increasing the force will also increase the acceleration.

• If the force is constant, an increase in mass causes a decrease in acceleration.

• A decrease in mass causes an increase in acceleration with a constant force.

• If the mass is constant, decreasing the force will also increasing the acceleration.
