Motion

Page 2: Force and Motion. Force Push or pull on an object

Force

• Push or pull on an object.

Page 3: Force and Motion. Force Push or pull on an object

Inertia

• Tendency of a motionless object to stay motionless, unless acted on by a force.

Page 4: Force and Motion. Force Push or pull on an object

Backward Push

• Force from behind that sets an object in motion.

Page 5: Force and Motion. Force Push or pull on an object

Gravity

• Force that pulls an object toward Earth.

Page 6: Force and Motion. Force Push or pull on an object

Friction• Objects resistance to move because another

resistance is acting in the opposite motion. (If an object is moving, the opposite is not moving; therefore, their forces are acting on each other causing an object to slow down).

Lubricant

• Material used so objects don’t stick to another, such as, oil, wax, grease, or Teflon.

Page 8: Force and Motion. Force Push or pull on an object

Diagram Arrows

• Arrows describing a force’s action on an object through a visual display:– Direction of force.– Magnitude/strength of

force. The longer the line the more strength of the force.

Page 9: Force and Motion. Force Push or pull on an object

Mass

• Amount of matter in an object. The greater the mass, the less force affects the objects. More force is needed to move more mass.

Page 10: Force and Motion. Force Push or pull on an object

Speed

• How far an object moves in a given period.

Formula:

Page 11: Force and Motion. Force Push or pull on an object

Velocity

• Measure of speed that accounts for direction of movement.

Page 12: Force and Motion. Force Push or pull on an object

Slope

• Distance covered while coming down from a height.

Page 13: Force and Motion. Force Push or pull on an object

Graph

• Compares different information in a pictorial representation, such as using bars, lines, and points.

Page 14: Force and Motion. Force Push or pull on an object

Acceleration

• Object’s increased speed of motion.

Page 15: Force and Motion. Force Push or pull on an object

Work

• In scientific terms: done only when a force moves an object.

• Force/energy is the ability to do work.

Page 16: Force and Motion. Force Push or pull on an object

Resistance Force

• A force such as gravity or friction.

Page 17: Force and Motion. Force Push or pull on an object

Air Resistance

• Gas molecules being pushed upon by a force.

Page 18: Force and Motion. Force Push or pull on an object

Types of Force

Page 19: Force and Motion. Force Push or pull on an object

Newton’s 1st Law of Motion(Law of Inertia)

• An object with no unbalanced force acting on it will either remain at rest, or continue moving at constant speed in a straight line unless a force acts on it.

Page 20: Force and Motion. Force Push or pull on an object

Newton’s 2nd Law of Motion(Law of acceleration)

• When an unbalanced force is applied to an object, it will accelerate in the direction the force moved it. Greater the force, the faster the object will move.

Newton’s 3rd Law of Motion

• For every action of force, there is an equal and opposite reaction of force.
