Forces & Motion

The overall force acting on an object after all the forces are combined is called a 

• net force
• unbalanced force
• balanced force

When the net force is zero what type of force is acting on the objects? 

• balanced force
• unbalanced force

When the resulting force is greater than zero what type of force is acting on the objects? 

• balanced force
• unbalanced force

A force that opposes the motion of objects that touch as they move past each other. 

• vector
• gravity
• friction 

A force that acts between any two masses is called: 

• friction
• vectors
• gravity

What is a measure of the change of velocity of a moving object?

• speed
• acceleration
• motion 
• velocity 

If the velocity vector and acceleration vectors are moving in the same direction then

• speed will increase.
• speed will decrease.
• speed will be constant. 

Which is not an example of acceleration?

• Driving at a constant speed 
• A bat hitting a ball
• Throwing a football 
• Kicking a soccer ball

Balanced forces always have a net force of 

• 10 N
• 0 W
• 10 W
• 0 N

The SI unit for force is 

• Watt (W)
• Power (P)
• Newton (N)
• Force (F)
