How is force defined according to Newton's first law?

• The rate of change of momentum

• The product of mass and acceleration

• The push or pull on an object that can cause it to accelerate

• The resistance of an object to a change in its state of motion

Which of the following is an example of a vector quantity?

What does a couple in physics refer to?

• Two forces of the same magnitude acting in the same direction

• Two forces of the same magnitude acting in opposite directions separated by a perpendicular distance.

• Two forces of different magnitudes acting at the same point

• Two forces of different magnitudes acting at different points

How would you describe the moment of a force?

• The tendency of a force to rotate an object about an axis

• The product of force and time

• The distance from the point of application of the force to a specified axis

• The sum of all forces acting on an object

What are the conditions for equilibrium in terms of moments?

• The sum of all forces must equal zero

• The sum of all moments must equal zero

• The sum of all forces must be greater than zero

• The sum of all moments must be greater than zero

According to Newton's First Law of Motion, what will happen to a body if no force acts upon it?

• It will slow down and eventually stop.

• It will change direction randomly.

• It will remain at rest or continue to move with a uniform velocity.

• It will begin to move in a circular path.

What is the unit of force in the Metric System?

• Joule (J)

• Pound (lb)

• Newton (N)

• Watt (W)
