Forces

What is defined as a push or pull

• force
• motion
• vector
• speed

The tendency to resist a change in motion is called

• Net Force
• Gravity
• Inertia
• Balanced Forces

Newton's 2nd Law of Motion gives us the formula, ____

• F = mv
• F = ma
• F = dt
• F = vt

How does friction affect speed?

• more friction decreases speed
• more friction increases speed
• less friction decreases speed
• less friction doesn't affect speed

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

• contact
• gravity
• friction

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 force holds the planets in motion around the sun?
