Question

newtons first law quick check
according to newtons first law of motion, an object in motion will stay in at the same speed and direction unless acted upon by what kind of force? (1 point)
an unbalanced force
inertia
a net force
a balanced force

Explanation:

Newton's First Law states that an object in motion remains in motion with the same speed and direction unless an unbalanced force acts on it. Inertia is the property of an object to resist changes in motion. A net force is the sum of all forces acting on an object. A balanced force means the sum of forces is zero, so no change in motion. An unbalanced force causes a change in motion.

Answer:

an unbalanced force
