Vocabulary
What is a characteristic of a moving object that is related to the mass and velocity of the object?
Momentum.
If you had four dogs pulling a sled, and two people in the sled, how could you increase the sled's acceleration? Two ways.
Add a dog, or take away a person.
Mass x Velocity.
What type of friction occurs when you swim in a pool?
Fluid Friction.
What is a push or a pull?
Force.
What is the combination of all the forces on an object?
Net Force.
If you had four dogs pulling a sled, and two people in the sled, how would you decrease the sled's acceleration? Two ways.
Take away a dog, or add a person.
Final Speed - Initial Speed/Time.
What type of friction occurs when you rub your palms together?
Sliding Friction.
What is a force that causes an object to move in a circular path?
Centripetal Force.
What is the resistance to the change in motion?
Inertia.
One object exerts a force on another object, then the second object exerts a force of equal strength in the opposite direction on the first object. Which law of motion is this?
Newton's Third Law of Motion.
What is the SI Unit for Force?
Newton (N).
What type of friction occurs when you skateboard on a ramp?
Rolling Friction.
What SI Unit is the strength of Force measured in?
Newton.
What are objects that orbit other objects in space called?
Satellites.
An object's acceleration depends on its mass and on the net force acting on it. Which law of motion is this?
Newton's Second Law of Motion.
What is the SI Unit for Momentum?
What type of friction occurs when you push a desk that does not move?
Static Friction.
What is a measure of the force of gravity on an object?
Mass.
What is the measure of the force of gravity on an object?
Weight.
An object at rest will stay at rest unless acted on by a nonzero net force. An object moving will stay moving unless acted on by a nonzero net force. Which law of motion?
Newton's First Law of Motion.
If the lioness has a Mass of 180kg, and a Velocity of 16 m/s to the right, what is her Momentum?
2880 kg x m/s.
Opposite the direction of motion.
What in the absence of outside forces like friction, the total momentum of objects that interact with each other does not change?
Law of Conservation of Mass.
