Ch. 2.3 Unbalanced Forces and Motion Test

When one object exerts a force on a second object, the second object exerts an equal force in the opposite direction on the first object is Newton's

• First Law of Motion

• Second Law of Motion

• Third Law of Motion

• Fourth Law of Motion

The acceleration of an object equals the net force divided by the object's mass is Newton's

• First Law of Motion

• Second Law of Motion

• Third Law of Motion

• Fourth Law of Motion

In a circular motion, a force that acts perpendicular to the direction of motion toward the center of the circle is

• net force

• gravitational force

• mass

• centripetal force

When a resting object is acted on by an unbalanced force, the object will ___________ in the direction of the unbalanced force.

• accelerate

• decelerate

• move in a circular path
• remain stationary

An object's speed will __________ when a net force acts in the same direction as the object's motion.

• oscillate

• increase (speed up)

• remain constant
• decrease

An object's speed will __________ when a net force acts in the opposite direction of the object's motion.

• increase
• remain the same
• decrease
• oscillate

A ball tied to a string and swung in a circle is an example of a/an ______________.

• linear motion
• uniform circular motion
• oscillatory motion
• random motion

In Newton's Second Law of Motion

• a= s/f

• meters/second (m/s)

• inches/second (in./s)

• kilometers/second² (km/s²)

Force is measured in

• Inches
