This type of forces results in a change in motion.
Unbalanced forces
This type of force opposes the motion of objects traveling through the air.
Air resistance
A baseball hit with a bat accelerates more than a bowling ball hit with a bat.
2nd Law
The more _________ you have, the more inertia you have.
Mass
A car with a mass of 1500 kg is traveling at 27 m/s when it suddenly hits a deer that is on the road. If the deer is sent forward at a speed of 338 m/s, what is the mass of the deer in kg?
120 kg
Sarah pushes a box with a force of 10 N to the right and Matt pushes with a force of 3 N to the left. Find the net force applied to the box.
7 N to the right
This is the fastest speed that an object will fall at and is reached when the force of gravity is equal to the force of air resistance.
Terminal velocity
A balloon flies forward when air quickly escapes it.

If the mass of a bulldozer is 1250 kg and it is moving at a speed of 20 m/s, how much momentum does it have?
25,000 kg*m/s
A book is resting on a table. The book has a mass of 15 kg. What is the NET FORCE acting on the book?
0 N
What two variables impact the strength of gravity between two objects?
Mass and distance
The bike you are riding hits a hole and stops quickly, but you fly forward.
1st Law
A car accelerates from 20 m/s to 60 m/s in 5 s. If the mass of the car is 150 kg, find the final momentum.
p = 9000 kg*m/s
