Force and Motion
How fast an object's position changes over time. Such as, "Chris can throw a baseball 55 mph.".
Speed
What is THE ABILITY TO DO WORK?
Any force requires this.......
Energy
_________________ occurs when two objects hit each other with a force.
Collision
Any push or a pull that causes an object to start moving, speed up, change direction, slow down, or stop.
Force
What causes heat when rubbing your hands together or when you apply brakes to your vehicle's tires?
Friction
The _______________ energy of a roller coaster is the energy it has because of its position(how high it is).
Potential or Stored
movement of energy from one object to another.
energy transfer
Squeezing together a spring and pulling back a sling shot are both examples of how to build _______________ energy.
Potential or Stored
_______________________ is when an object changes its speed and/or direction.
An object is always doing this as long as their speed or direction is changing.
Acceleration or Accelerating
When you ride a bicycle and decide to increase your speed, your _______________ energy increases as well.
Kinetic or energy of motion
More _________ is transferred from the object with greater momentum to the object with lesser momentum.
Energy
What is velocity?
The speed and direction of an object.
Objects in motion tend to stay in motion because of the property of ______________.
All objects have this property.
Inertia
How can the speed, or kinetic energy, of a dropped ball be INCREASED?
Increase the height from which it is dropped from to give the ball more potential/stored energy.
Energy is neither _____________ nor __________________, it can only transfer or transform.
Created ; destroyed
Force that pulls objects toward the center of the Earth.
Gravity
The acceleration of an object depends on two factors. What are they?
1) The amount of force applied on the object
2.) The weight of an object
The kinetic energy, or the energy that an object has because it is in motion, depends on two factors.
What are they?
1.)The speed of the object.
2.) The mass or weight of the object.
During a collision, _____________ causes the objects to rapidly rub against each other resulting in some of the energy being transferred into __________ and ____________ energy.
Friction; heat; sound
Method of measuring how easy or difficult it is to stop a moving object.
Momentum
