Force of Gravity Pre-Lab Are the forces of gravity acting on the two students different? What is another term that means the force of gravity? Weight –

Gravity and Free Fall.  Gravity - attraction between objects with mass  Gives weight  Causes free fall Gravity.

 F = ma  m is measured in kg  a is measured in m/s 2  F is measured in kg m/s 2, called a Newton (N)

REVISION What two parts make up the stopping distance of a vehicle?

Accelerated Motion. Newton’s Second Law of Motion (Law of Force)- Net force acting on an object causes the object to accelerate in the direction of the.

Weight – Mass Experiment. Purpose To measure the mass of each object in grams using the triple beam balance. To convert the mass in grams to kilograms.

Newton’s second law. Acceleration(m /s 2 ) Mass (kg) The acceleration of an object equals the net force divided by the mass. Net force (N) Newton’s second.

Newton’s Second Law of Motion. 2 nd Law of Motion  The net (total) force of an object is equal to the product of its acceleration and its mass.  Force.

PRBA-COSTHA Project for Securing Shock Data on Large Lithium ion Battery Shipments

T4 Shock Test Purpose: “simulate possible impacts during transport” 150 g and 50 g forces far exceed severe transport conditions Review of available test shock data from transport Review of lithium battery testing standards Industry plans for securing additional shock data

Comparison of Shock Tests UN Manual SAE J2464 RTCA DO-160F Airborne Equipment Acceleration (gn) 50 25 20 Pulse Form Half sine Saw tooth Duration (ms) 11 15 Total # shocks 18 3 repeats 3 axes +/- directions 6 3 orthogonal axes Mass >12 kg Mass limit unspecified

PRBA and COSTHA Data Analysis and Project Data logger Engine shipment was selected for test as surrogate for battery shipment Engine has similar weight and uses similar mounting and support during transport Acceleration (G) +2.93/-2.49 +2.19/-0.58 +1.51/-0.40 +0.55/-1.45 +0.33/-1.30
