Energy
stored energy (something that’s going to happen) that depends on what position the object/situation is in. Often Energy is being transferred from this type of energy to Kinetic Energy.
An object at rest tends to stay at rest, and an object in motion tends to stay in motion, with the same direction and speed.
What is Newton's First Law?
The resistance of motion when one object rubs against another, in the opposite direction. The motion that slows things down or stops objects.
What is Friction
A push or pull
What is a force?
What is velocity?
A man pulls a bow and arrow back to take aim.
This is an example of _______________ energy.
What is Potential Energy?
For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object.
What is Newton's third Law?
The ball will _________ or _________ due to Friction
What is slow down or stop?
These forces result in movement.
What are unbalanced forces?
Distance over time
What is speed?
Energy in motion. Or things moving. Often Energy is being transferred from Potential Energy to this type of energy.
What is Kinetic Energy?
The objects acceleration equals the force on the object divided by the object's mass. F=ma
What is Newton's 2nd Law?
The resistance created by two objects sliding against each other. This motion slows the object down or stops the object.
What is sliding friction?
Two forces acting in opposite directions on an object, and equal in size. Anytime there is this type of force on an object, the object stays still or continues moving at the same speed and in the same direction.
What are balanced forced?
Speeding up, Slowing Down, or changing directions
What is acceleration?
An airplane flying around the sky is an example of _________ energy.
What is Kinetic Energy?
This is a measurement of mass in motion. Any object that is moving has This. The more mass something has the more ____________ it has. p=mv
What is momentum?
Friction which happens between a stationary object and the surface on which it's resting.
What is static friction?
Forces that change the motion of an object. This happens in two ways. If an object is at rest and this force pushes or pulls the object, it will move. These forces can also change the speed or direction of an object that is already in motion.
What are unbalanced forces?
This depends on the the mass of the object. An example would a bowling ball and a golf ball dropped on your toes. The bowling ball would hurt much more.
What is the Force of Gravity?
What happens to the energy when a ball is dropped?
An object at rest will remain at rest and an object in motion will remain in motion.
What is inertia?
This type of friction involves a fluid or air. The air resistance on an airplane or water resistance on a boat are examples of this friction.
What is fluid friction?
A force that is the support force exerted upon another object which is in contact with another stable object.
Example a book resting on a table. The table is exerting a force on the book in order for it to support the book.
What is a normal force?
All object on earth fall at 9.8m/s/s. This means that when object dropped from the same height will hit the ground a the same rate.
What is the acceleration of gravity?
