Newton's Law of Motion

An object at rest will _______ if no outside forces are applied.

• Stay at rest
• Increase Velocity
• Decrease Mass

The SI units for force are...

• Kilograms
• Newtons
• Meters per second
• Pounds

According to Newton’s first law of motion, a moving object that is not acted on by an unbalanced force will

• remain in motion.
• eventually come to a stop.
• change its momentum.
• accelerate.

How does Newton’s third law explain how a rocket takes off?

• The rocket’s acceleration is positive, while the gasses acceleration is negative but the direction is the same. 
• The rocket is at rest until ignition.
• The hot gasses move in one direction, while the rocket moves in the opposite direction but with equal force.
