Question

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)
a balanced force
a net force
an unbalanced force
inertia

Explanation:

Newton's First Law of Motion states that an object in motion will stay in motion at the same speed and direction unless acted upon by an unbalanced force. A balanced force means the net force is zero and won't change the object's motion. Net force is just the total force. Inertia is the property of an object to resist changes in motion, not a force.

Answer:

an unbalanced force
