Physical Science Test - Chapter 5: Dynamics

What is the unit of force?

• Kilogram
• Meter
• Pascal
• Newton

IF AN OBJECT REMAINS AT CONSTANT SPEED IN THE SAME DIRECTION, THAN THE FORCES ARE KNOWN TO BE:

• BALANCED

• UNBALANCED

• INCREASING

• DECREASING

How will this object move? 

• It won't move. 
• It will move to the right. 
• It will move to the left. 
• It will move up. 

The force needed to move an object depends upon:

• the mass of the object
• the volume of the object
• the density of the object
• the shape of the object

If an object is accelerating, then the forces acting on it must be:

• balanced
• unbalanced
• increasing
• zero

Forces that are equal in magnitude but opposite in direction are:

• unbalanced
• balanced
• increasing
• decreasing

A block is pushed from four sides with forces of different magnitude, as shown in the picture. In which direction will the block move?

• east
• west
• north
• south

How will this object move? 

• It won't move. 
• It will move to the right. 
• It will move to the left. 
• It will move in both directions. 

If an object is accelerating, then the forces acting on it must be:

• balanced
• unbalanced
• increasing
• zero

Who developed mathematical equations describing how forces affect motion?

• Aristotle

• Archimedes

• Galileo

• Newton
