A car is driving East, moving at 70 mph. This is an example of the car's...
What is velocity?
The change in one' object's position compared with another object's position
What is Relative Motion
Newton's first law states that
What is an object in motion stays in motion and an object at rest stay at rest unless acted on by an outside force?
This is a non contact force
What is gravity?
I am going to push Tatum in a swing. I pull her up very high to start. This is what kind of energy?
What is potential energy.
What is the relative motion of a person who is running past you?
What is the person is moving ahead of you?
One way an object can move
What is straight
This is another non contact force
What is magnetism
When a roller coaster is speeding down a hill
What is kinetic energy?
What two things need to be measured to determine an object's velocity?
What are speed and direction?
A second way an object can move
What is in a curved path?
Newton's 3rd law states that
What is for every action there is an equal and opposite reaction?
This is what happens if balanced forces are applied to a moving object
What is the object will keep moving at the same speed and in the same direction?
Explain how a rocking chair using potential and kinetic energy
What is potential energy when it is way back and way forward and stops for a split second? What kinetic energy when it is in motion
What does distance have to do with gravity?
What is the force of gravity is stronger between objects that are closer together. As the objects move farther apart, there is less gravity.
The third way an object can move
What is back and forth?
An example of Newton's 2nd law
What is: answers will vary
This is what happens to an object that has an unbalanced force acting upon it
What is it will move in the direction of the greater force?
Give a statement about a measure of kinetic and potential energy.
The kinetic energy in a object will never be greater than the potential energy.
What does mass have to do with gravity?
What is the force of gravity is stronger between more massive objects. As the masses of the objects are reduced, there is less force of gravity between the objects.
This is like "your point of view" when something is moving
What is Frame of Reference?
An example of Newton's 3rd law:
What is: answers will vary
This force will stop or slow an object down
What is friction?
an example of potential and kinetic energy in my life
What is: responses will vary
