Question

true or false
true
false an object can experience multiple forces but not accelerate
true
false an object can be in motion but have zero net force
true
false an unbalanced force is not needed to change an objects motion
true
false when you push a wall, the wall pushes back on you with an equal and opposite force
true
false an objects intertia is determined by the size of the object

Explanation:

1. First statement: According to Newton's second law \(F = ma\). If the net force \(F_{net}=0\) (even if there are multiple forces acting, but they cancel each other out), then \(a = 0\). So an object can experience multiple forces but not accelerate.
2. Second statement: By Newton's first law, an object in motion will stay in motion with a constant velocity (zero - acceleration state) when \(F_{net}=0\).
3. Third statement: By Newton's first law, \(F_{net}

eq0\) (unbalanced force) is required to change an object's state of motion (i.e., to change its velocity, either magnitude or direction or both).

1. Fourth statement: According to Newton's third law, for every action, there is an equal and opposite reaction. When you push a wall (action force), the wall pushes back on you (reaction force) with an equal and opposite force.
2. Fifth statement: An object's inertia is determined by its mass, not its size.
