Force and Motion Review

A push or pull that can change the position or motion of an object/material is --

• magnetism

• motion

• force

Two students were pulling on the rope below with the same amount of force. The man increased the amount of force he was using by 2 N and the woman increased the amount of force she was using by 4 N. Which BEST describes the motion that resulted after they increased force?

• The both moved farther from one another

• The man moved towards the woman

• The woman moved towards the man

• They both moved farther from one another

Which of the following statements is true? 

• Balanced forces cause a change in motion. 
• Unbalanced forces cause a change in motion. 
• Forces do not effect the change in motion. 

During tug-of-war, one side of students were pulling with a force of 120 N and the other side was pulling with a force of 80 N. Were these forces balanced or unbalanced? 

• Balanced 
• Unbalanced 

In the speed vs time graph, what is happening to the object's speed?

• The object's speed is increasing. 
• The object's speed is decreasing. 
• The object's speed is the same (constant). 

If a car travels 80 miles in 2 hours, what is the car's speed?

• 30 mi/hr
• 40 m/s
• 45 m/s
• 40 mi/hr

Which line on the position vs time graph represents (shows) an object returning or going towards the starting place?

• A
• B
• C
• D

When objects remain in the same place, it is called...

• gravity

• friction

• balanced forces

• unbalanced forces

Speed can be found by calculating...

• acceleration/ velocity

• friction/ gravity

• momentum/ time

• distance/ time

When an object is getting faster, it is called...

• potential energy

• kinetic energy

• acceleration

• deceleration
