In the context of Newton's First and Second Laws, what is the force with which a moving object hits another object called?

A $5 \mathrm{kg}$ object is acted upon by two forces: $10 N$ to the right and $6 N$ to the left. According to Newton's Second Law, what is the magnitude of the resultant force acting on the object?

In an Atwood machine consisting of two masses $m_1$ and $m_2$ connected by a light, inextensible string over a frictionless pulley, which of the following correctly gives the acceleration $a$ of the system (take upward as positive for $m_1$)?

If a block is moving to the left at a constant velocity, what can one conclude about the forces acting on it?

In a game, a block is being pushed to the right with a force of $10N$. Which of the following forces applied to the left would result in balanced forces on the block?

Which of the following lists the three basic steps in the NSC collision prevention formula as applied to $N{e}^{1}wton’s$ First and $S{e}^{2}cond$ Laws?

According to Newton's First and Second Laws, what happens to the acceleration $a$ of a car in a frontal collision if the net force $F\_\mathrm{net}$ acting on it is large and acts in the opposite direction of its initial motion?

According to Newton's First Law, when an object is in motion and no net external force acts on it, what will happen to its motion?

According to Newton's First Law, an object cannot remain at rest unless which of the following conditions is satisfied?

According to Newton's Second Law, an increase in $F$, not resistance, results in an increase of load.
