Explain the difference between kinetic and potential energy.
Kinetic energy is energy when something is moving. Potential energy is energy that is stored up waiting to be released.
The math formula to calculate potential energy is: of an object about to fall is (PE=
PE = weight (of the object) x height (where the object is above the ground)
Energy of moving microscopic particles of matter is…[Friction creates this.]
heat energy.[The faster the particles of a substance are moving, the warmer the substance is.]
Ryan Miller saves an attempt on goal hit by Crosby with 20N of force. The ice exerts 2 N of friction on the puck. What is the net force? (What force is left over after the friction is taken away?)
Speed = distance divided by time.Ex. =>miles per hour =>meters per second
Ryan Miller kneels in front of the net. His pads put 30N of force on 6 square feet of area. How much pressure is exerted on the ice? Pressure = force divided by area
Pressure = force / areaP = 30N / 6 sq. ft. P = 5N per sq. ft
Ryan Miller saves a shot from Crosby hit with 10N of force from a distance of 30 m. How much work did Crosby do in that shot? Work = force x distance
Acceleration = (final speed - initial speed) divided by timeEx. (60 mph - 10mph) / 10 secacceleration = 50mph / 10 secacceleration = 5mph/sec
What word is used instead of saying “Newton’s First Law of Motion?”
Newton’s Second Law says force is equal to mass times …f = m x ?
