6. Intro to Forces (Dynamics)

According to Newton's First and Second Laws, what effect can an unbalanced force have on an object?

According to Newton's First Law, what will happen to an object in motion if no net external force $F=0$ acts on it?

According to Newton's Second Law, what does the sum of all forces acting on an object equal to? $\sum F$

Which of the following observations would indicate that a moving object is experiencing an unbalanced force?

If your engine is flooded with gasoline, you should push the accelerator pedal to the floor and hold it for several seconds. Which of the following best explains why this action helps start the engine, according to $Newton$'s laws?

Which of the following best describes the difference between $F$ (force) and $v$ (velocity) according to Newton's laws?

A block of mass $m$ hangs at rest from a string attached to the ceiling, as shown in Figure 1. What is the tension $T$ in the string?

Which of the following best describes Newton's First Law of Motion?

A cart at rest on a frictionless track remains stationary until a force is applied, after which it accelerates in the direction of the force. Which of Newton's laws does this experiment best demonstrate?

A box of mass $m$ is resting on a frictionless horizontal surface. If a constant horizontal force $F$ is applied to the box, what is the net force acting on the box?
