Forces

Terminal velocity is 

• zero motion
• unbalanced force
• maximum speed an object can reach
• air resistance  

This type of force is an attraction between two objects

• contact
• gravity
• friction

This type of force resist motion between two surfaces that are pressed together

• contact
• gravity
• friction

If the net force is equal to zero, the forces acting on the object are

• balanced

• unbalanced

Balanced forces do not change the objects speed or 

• direction
• distance 
• time
• mass

The unit of force is

• m/s
• m/s^2
• newton
• kg

What is defined as a push or pull?

• force

• motion

• vector

• speed

If I slowly roll a ball down the hallway, why does it eventually stop?

• Because of Newton's First Law
• Friction and Air Resistance
• Inertia
• It wouldn't stop, it would keep going until it hits a wwall.

If forces on an object are balanced, the object is...

• Moving
• Not moving

Which of the following is the best example of Newton's First Law of Motion?

• Jessica's body flies forward after she hits the brakes

• Jessica drives a car

• Jessica is at a road crossing

• Jessica is sleeping
