SOL 5.2 & 5.3 Force, motion, and energy
SOL 5.2 - Force, Motion, and Energy --Energy can take many forms. Key ideas include energy is the ability to do work or to cause change; there are many different forms of energy; energy can be transformed; energy is conserved. SOL 5.3 Motion -- Key concepts: moving objects have kinetic energy; motion is described by an object’s direction and speed; changes in motion are related to net force and mass; when objects collide, the contact forces transfer energy and can change objects’ motion; friction is a force that opposes motion. CENTRAL IDEA -Energy can occur in different forms, can be transformed from one form to another, but it cannot be created or destroyed. Energy causes change & can be transformed. Energy is the ability to cause change or do work. Energy can be transferred in various ways and between objects. Energy is the ability to cause change and that change can take multiple forms. Energy takes many forms such as motion, light, sound, electrical and magnetic fields, and thermal energy. Energy cannot be created or destroyed; however, it can transform from one form into another. Energy can take many forms such as thermal, radiant, mechanical, and electrical. Energy can change forms but cannot be created or destroyed. For example, electrical energy is transformed into thermal energy when a stove is turned on. The electrical energy does not just disappear and thermal energy does not just appear out of nowhere. work Energy can be transformed from one form to another to do work. Work, in a scientific sense, is defined as a force acting upon an object, causing that object to move in the direction of the force. Energy can be moved from place to place by moving objects, or through sound, light, or electric currents. Central Idea: An object's motion is described by its direction and the speed. Motion = Kinetic Energy Forces between objects can cause a change in motion. When two objects interact, each exerts a force on the other. These forces can transfer energy between objects which can cause changes in their motion. Moving objects have kinetic energy, which is the energy of motion. The motion of an object is described by its direction and speed. A change in motion is related to net force and mass. FORCES The net force is the combination of all the forces acting on an object. Whether an object stays still or moves often depends on the effects of multiple pushes or pulls. An object at rest typically has multiple forces acting on it, but they add to give zero net force on the object. Forces that do not sum to zero net force can cause changes in the object's speed or direction of motion. When objects collide, the energy from one object transfers to another object. That transfer in energy can change an object's speed and or direction . Motion is described as an object’s direction and speed. The more massive an object, the less effect a given force will have on that object. Speed describes how fast an object is moving. Unless acted on by a force, objects in motion tend to stay in motion and objects at rest remain at rest. A force is any push or pull that causes an object to move, stop, or change speed or direction With objects of the same mass, the greater the force, the greater the change in motion. The more massive an object, the less effect a given force will have on that object. FRICTION Friction is a force that opposes the motion of an object.

CENTRAL IDEA -Energy can occur in different forms, can be transformed from one form to another, but it cannot be created or destroyed.

Energy causes change & can be transformed.

Energy is the ability to cause change or do work. Energy can be transferred in various ways and between objects.

Energy is the ability to cause change and that change can take multiple forms.
Energy takes many forms such as motion, light, sound, electrical and magnetic fields, and thermal energy.
Energy cannot be created or destroyed; however, it can transform from one form into another.
Energy can take many forms such as thermal, radiant, mechanical, and electrical.
Energy can change forms but cannot be created or destroyed.
- For example, electrical energy is transformed into thermal energy when a stove is turned on.
- The electrical energy does not just disappear and thermal energy does not just appear out of nowhere.

work

Energy can be transformed from one form to another to do work.
Work, in a scientific sense, is defined as a force acting upon an object, causing that object to move in the direction of the force.
Energy can be moved from place to place by moving objects, or through sound, light, or electric currents.

Central Idea: An object's motion is described by its direction and the speed.

Motion =
Kinetic Energy

Forces between objects can cause a change in motion. When two objects interact, each exerts a force on the other. These forces can transfer energy between objects which can cause changes in their motion.

Moving objects have kinetic energy, which is the energy of motion.
- The motion of an object is described by its direction and speed.
- A change in motion is related to net force and mass.

FORCES

The net force is the combination of all the forces acting on an object.
Whether an object stays still or moves often depends on the effects of multiple pushes or pulls.
- An object at rest typically has multiple forces acting on it, but they add to give zero net force on the object.
- Forces that do not sum to zero net force can cause changes in the object's speed or direction of motion.
When objects collide, the energy from one object transfers to another object.
- That transfer in energy can change an object's speed and or direction .
Motion is described as an object’s direction and speed.

The more massive an object, the less effect a given force will have on that object.

Speed describes how fast an object is moving.
Unless acted on by a force, objects in motion tend to stay in motion and objects at rest remain at rest.
A force is any push or pull that causes an object to move, stop, or change speed or direction
With objects of the same mass, the greater the force, the greater the change in motion.
- The more massive an object, the less effect a given force will have on that object.

FRICTION

Friction is a force that opposes the motion of an object.
