Forces are described by their __________ & __________ Strength & direction
Greatest velocity that a falling object can reach. Terminal Velocity
This is a product of an object’s mass & velocity. Momentum
This is the tendency of an object to resist a change in motion. Inertia
This law says that gravity acts between all objects in the universe due to their mass. Law of Universal Gravitation
This law states that an object at rest will stay at rest unless acted on by an outside force. Newton’s 1 st Law of Motion
As mass increases; inertia _______________. Increases
Force = mass x acceleration. Newton’s 2 nd Law
What force causes a bouncy ball to rise back into the air after it has hit the ground? Reaction Force
Which law says that for every action there is an equal an opposite reaction force. Newton’s 3 rd Law
A speedboat pulls a 55-kg water- skier. The force causes the skier to accelerate at 2.0 m/s 2. Calculate the net force that causes this acceleration. 110 Newtons
Find the momentum of a 6 kg bowling ball that is moving at 10 m/s down the alley toward the pins. 60 kg m/s
A marble at rest is dropped from a tall building. The marble hits the ground with a velocity of 98m/s. How long was the marble in the air? 10 seconds
Find the acceleration of a 7kg mass if a force of 63 N is used to move it toward earth. 9 m/s/s
If Mr. Incredible has a mass of 15kg on earth. What would his mass and weight be on Mars. The acceleration due to gravity of mars is 3.8. Mass = 15 kg Weight = 57 N
___________ is when the only force acting on an object is gravity. Free Fall
If two erasers were released at the same time but one was dropped and the other was thrown, which would hit the ground first. The same time
Kg x m/s is a unit of what? Momentum
As mass increases; acceleration ________________. Decreases
Objects at rest stay at rest will stay at rest unless __________ Acted on by an outside force
Why don’t objects stay in motion forever? Friction
Which will hit the ground first a 2 kg golf ball or a 10 kg bowling ball? They will hit at the same time
Why do some objects on earth fall faster than others? Air Resistance
A rock at rest falls off a tall cliff and hits the valley below after 3. 5s. What is the rock’s velocity as it hits the ground? 34.3 m/s
Why don’t action reaction forces cancel out? They do not act on the same object

Chapter 13 Forces.
FORCE Chapter 10 Text. Force A push or a pull in a certain direction SI Unit = Newton (N)
Newton’s Laws of Motion (chapter 4). Newton’s 1 st Law of Motion An object at rest will remain there unless a force acts on it; likewise, a moving object.
Newton’s Laws of Motion
Physics Notes Newton’s Laws of Motion
Chapter 10 Forces. Force and Net Force Force is a push or a pull on an object. Net force is the total force on an object.
