__________ is the sum of all forces acting on an object. It is capable of accelerating a mass. 

• friction

• applied force

• net force
• gravitational force

If the velocity of the object is to the right, the object will _____.

• speed up

• slow down

• turn

Answer explanation

Since the net force is to the right, that means the acceleration is to the right. When acceleration and velocity are in the same direction, the object will speed up!
